feat(slot-reservations): Add expansionRate parameter to support contract changes
Adds `expansionRate` field to the `StorageRequest` object, to mirror the object in the contracts.

The CodexClient api module uses a default value of 100, which means that all SPs will be available to reserve slots immediately, when the functionality is finally implemented. It was chosen to provide as little disruption to existing as possible, and may change in the future.

The default value for the REST API endpoint was 60, meaning 60% of the total time before expiry will have all addresses eligible to fill the slot.

feat: add `--payout-address` (#870)
* feat: add `--payout-address`

Allows SPs to be paid out to a separate address, keeping their profits secure.
Supports https://github.com/codex-storage/codex-contracts-eth/pull/144 in the nim-codex client.

* Remove optional payoutAddress

Change --payout-address so that it is no longer optional. There is no longer an overload in `Marketplace.sol` for `fillSlot` accepting no `payoutAddress`.

* Update integration tests to include --payout-address

* move payoutAddress from fillSlot to freeSlot

* Update integration tests to use required payoutAddress

- to make payoutAddress required, the integration tests needed to avoid building the cli params until just before starting the node, otherwise if cli params were added ad-hoc, there would be an error after a non-required parameter was added before a required parameter.

* support client payout address

- withdrawFunds requires a withdrawAddress parameter, directs payouts for withdrawing of client funds (for a cancelled request) to go to that address.

* fix integration test

adds --payout-address to validators

* refactor: support withdrawFunds and freeSlot optional parameters

- withdrawFunds has an optional parameter for withdrawRecipient
- freeSlot has optional parameters for rewardRecipient and collateralRecipient
- change --payout-address to --reward-recipient to match contract signature naming

* Revert "Update integration tests to include --payout-address"

This reverts commit 8f9535cf35b0f2b183ac4013a7ed11b246486964.
There are some valid improvements to the integration tests, but they can be handled in a separate PR.

* small fix

* bump contracts to fix marketplace spec

* bump codex-contracts-eth, now rebased on master

* bump codex-contracts-eth

now that feat/reward-address has been merged to master

Update contract (#734)
* Update codex-contracts-eth

* contracts: update G2Point definition

* integration: disable automatic advancing of time

reason: makes reasoning about timing in tests harder,
because the period is set to 60 seconds in the
marketplace configuration, but this code switches to
a new period every 500 milliseconds

* integration: fix parameters of marketplace payouts test

* integration: update test settings

* integration: fix typo

* integration: workaround for hardhat issue

Subscriptions expire after 5 minutes when using
websockets. Use http and polling instead.

* integration: remove origDatasetSizeInBlocks

* integration: fix proof parameters for test

* integration: do not log output by default

* integration: fix failure rate in test

* integration: fix warning

* integration: include clock in logs

* integration: allow for more periods

5 periods was cutting it close, if we get too much
pointer downtime, then the test would fail

feat: create logging proxy (#663)
* implement a logging proxy

The logging proxy:
- prevents the need to import chronicles (as well as export except toJson),
- prevents the need to override `writeValue` or use or import nim-json-seralization elsewhere in the codebase, allowing for sole use of utils/json for de/serialization,
- and handles json formatting correctly in chronicles json sinks

* Rename logging -> logutils to avoid ambiguity with common names

* clean up

* add setProperty for JsonRecord, remove nim-json-serialization conflict

* Allow specifying textlines and json format separately

Not specifying a LogFormat will apply the formatting to both textlines and json sinks.

Specifying a LogFormat will apply the formatting to only that sink.

* remove unneeded usages of std/json

We only need to import utils/json instead of std/json

* move serialization from rest/json to utils/json so it can be shared

* fix NoColors ambiguity

Was causing unit tests to fail on Windows.

* Remove nre usage to fix Windows error

Windows was erroring with `could not load: pcre64.dll`. Instead of fixing that error, remove the pcre usage :)

* Add logutils module doc

* Shorten logutils.formatIt for `NBytes`

Both json and textlines formatIt were not needed, and could be combined into one formatIt

* remove debug integration test config

debug output and logformat of json for integration test logs

* Use ## module doc to support docgen

* bump nim-poseidon2 to export fromBytes

Before the changes in this branch, fromBytes was likely being resolved by nim-stew, or other dependency. With the changes in this branch, that dependency was removed and fromBytes could no longer be resolved. By exporting fromBytes from nim-poseidon, the correct resolution is now happening.

* fixes to get compiling after rebasing master

* Add support for Result types being logged using formatIt

Workaround for Hardhat last block timestamp bug (#644)
* Workaround for Hardhat timestamp bug

Likely due to a Hardhat bug in which the callbacks for subscription events are called and awaited before updating its local understanding of the last block time, Hardhat will report a block time in the `newHeads` event that is generally 1 second before the time reported from `getLatestBlock.timestamp`. This was causing issues with the OnChainClock's offset and therefore the `now()` used by the `OnChainClock` would sometimes be off by a second (or more), causing tests to fail.

This commit introduce a `codex_use_hardhat` compilation flag, that when set, will always get the latest block timestamp from Hardhat via the `getLatestBlock.timestamp` RPC call for `OnChainClock.now` calls. Otherwise, the last block timestamp reported in the `newHeads` event will be used.

Update the docker dist tests compilation flag for simulated proof failures (it was not correct), and explicitly add the `codex_use_hardhat=false` for clarity.

* enable simulated proof failures for coverage

* comment out failing test on linux -- will be replaced

* bump codex contracts eth

* add back clock offset for non-hardhat cases

* bump codex-contracts-eth

increases pointer by 67 blocks each period increase

* Add `codex_use_hardhat` flag to coverage tests

Slot queue (#455)
## Slot queue
Adds a slot queue, as per the [slot queue design](https://github.com/codex-storage/codex-research/blob/master/design/sales.md#slot-queue).

Any time storage is requested, all slots from that request are immediately added to the queue. Finished, Canclled, Failed requests remove all slots with that request id from the queue. SlotFreed events add a new slot to the queue and SlotFilled events remove the slot from the queue. This allows popping of a slot each time one is processed, making things much simpler.

When an entire request of slots is added to the queue, the slot indices are shuffled randomly to hopefully prevent nodes that pick up the same storage requested event from clashing on the first processed slot index. This allowed removal of assigning a random slot index in the SalePreparing state and it also ensured that all SalesAgents will have a slot index assigned to them at the start thus the removal of the optional slotIndex.

Remove slotId from SlotFreed event as it was not being used. RequestId and slotIndex were added to the SlotFreed event earlier and those are now being used

The slot queue invariant that prioritises queue items added to the queue relies on a scoring mechanism to sort them based on the [sort order in the design document](https://github.com/codex-storage/codex-research/blob/master/design/sales.md#sort-order).

When a storage request is handled by the sales module, a slot index was randomly assigned and then the slot was filled. Now, a random slot index is only assigned when adding an entire request to the slot queue. Additionally, the slot is checked that its state is `SlotState.Free` before continuing with the download process.

SlotQueue should always ensure the underlying AsyncHeapQueue has one less than the maximum items, ensuring the SlotQueue can always have space to add an additional item regardless if it’s full or not.

Constructing `SlotQueue.workers` in `SlotQueue.new` calls `newAsyncQueue` which causes side effects, so the construction call had to be moved to `SlotQueue.start`.

Prevent loading request from contract (network request) if there is an existing item in queue for that request.

Check availability before adding request to queue.

Add ability to query market contract for past events. When new availabilities are added, the `onReservationAdded` callback is triggered in which past `StorageRequested` events are queried, and those slots are added to the queue (filtered by availability on `push` and filtered by state in `SalePreparing`).

#### Request Workers
Limit the concurrent requests being processed in the queue by using a limited pool of workers (default = 3). Workers are in a data structure of type `AsyncQueue[SlotQueueWorker]`. This allows us to await a `popFirst` for available workers inside of the main SlotQueue event loop

Add an `onCleanUp` that stops the agents and removes them from the sales module agent list. `onCleanUp` is called from sales end states (eg ignored, cancelled, finished, failed, errored).

Add a `doneProcessing` future to `SlotQueueWorker` to be completed in the `OnProcessSlot` callback. Each `doneProcessing` future created is cancelled and awaited in `SlotQueue.stop` (thanks to `TrackableFuturees`), which forced `stop` to become async.
  - Cancel dispatched workers and the `onProcessSlot` callbacks, prevents zombie callbacks

#### Add TrackableFutures
Allow tracking of futures in a module so they can be cancelled at a later time. Useful for asyncSpawned futures, but works for any future.

### Sales module
The sales module needed to subscribe to request events to ensure that the request queue was managed correctly on each event. In the process of doing this, the sales agents were updated to avoid subscribing to events in each agent, and instead dispatch received events from the sales module to all created sales agents. This would prevent memory leaks on having too many eventemitters subscribed to.
  - prevent removal of agents from sales module while stopping, otherwise the agents seq len is modified while iterating

An additional sales agent state was added, `SalePreparing`, that handles all state machine setup, such as retrieving the request and subscribing to events that were previously in the `SaleDownloading` state.

Once agents have parked in an end state (eg ignored, cancelled, finished, failed, errored), they were not getting cleaned up and the sales module was keeping a handle on their reference. An `onCleanUp` callback was created to be called after the state machine enters an end state, which could prevent a memory leak if the number of requests coming in is high.

Move the SalesAgent callback raises pragmas from the Sales module to the proc definition in SalesAgent. This avoids having to catch `Exception`.
  - remove unneeded error handling as pragmas were moved

Move sales.subscriptions from an object containing named subscriptions to a `seq[Subscription]` directly on the sales object.

Sales tests: shut down repo after sales stop, to fix SIGABRT in CI

### Add async Promise API
  - modelled after JavaScript Promise API
  - alternative to `asyncSpawn` that allows handling of async calls in a synchronous context (including access to the synchronous closure) with less additional procs to be declared
  - Write less code, catch errors that would otherwise defect in asyncspawn, and execute a callback after completion
  - Add cancellation callbacks to utils/then, ensuring cancellations are handled properly

## Dependencies
- bump codex-contracts-eth to support slot queue (https://github.com/codex-storage/codex-contracts-eth/pull/61)
- bump nim-ethers to 0.5.0
- Bump nim-json-rpc submodule to 0bf2bcb
