1. use `ProviderError` to catch contract errors instaed of `JsonRpcProviderError`.
2. Add tests for `isProofRequired`, `willProofBeRequired`, and `getProofEnd` when slot is empty (and is call is reverted)
3. bump nim-ethers to branch that has new `reverts` API and `ProviderError` support.
4. Update to new `reverts` API.
Support storage contract parameters to free slots after too many proofs missed, as well as fail a contract after too many slots have been freed.

Remove `isSlotCancelled` and `isCancelled` from proving, as it did not fit in the module.
Update the proving module to not rely on checking the contract to understand if a request was cancelled. Instead, `proofEnd` was modified in `dagger-contracts` such that it returns a past timestamp when the contract is cancelled. This successfully removes
- remove RequestState as no longer being used
- remove RequestState check on purchase timeout
- add tests for `withdrawFunds` and `subscribeRequestCancelled`
- update `dagger-contracts` so that `RequestCancelled.requestId` property is indexed in the event
- rename `ContractId` to `SlotId`
- rename `Proving.contracts` to `Proving.slots`
- change signatures of `isSlotCancelled` and `isCancelled` to use `SlotId` and `RequestId` types, respectively.
- change all references to `RequestId`, `SlotId`
Add or remove proof requirements when a request contract’s state changes. When a request sale has completed (for a slot), the host who purchased that slot now must provide regular proofs for the data they are contracted to hold. This is now enforced by adding the slotId to the HashSet of Ids for which to require proofs. When a request has been cancelled (not all slots were filled before the request expired), proofs no longer need to be provided and the slotId is removed from teh HashSet.
Add `isCancelled` and `isSlotCancelled` checks to query the contract state without relying the on the state context variable in the contract. Because contract state can only be updated in a transaction, and the client withdrawing funds is responsible for changing the contract state to “Cancelled”, the `isCancelled` and `isSlotCancelled` functions were introduced to check the state regardless of whether or not the client had already withdrawn their funds.
When a request for storage times out (not enough slots filled), the client will initiate a withdraw request to retrieve its funds out of the contract, setting the state of the request to RequestState.Cancelled. The client will also emit a RequestCancelled event for others to listen to (ie hosts will need to listen for this event to withdraw its collateral).
Add unit test that checks for emission of RequestCancelled after request is purchased request expires.
Update dagger-contracts dependency to commit that holds the changes supporting withdrawing of funds.
Increase blocksize from ~8KiB to ~64KiB and remove useless unbounded prefetching on download
* increased upload/download speed on my Win10 Zen3 box to 50/150 MB/s (with FSStore)
* made manifest files 8x smaller
* two more changes in the tests to make them pass
Closes#263
* upgrading nimbus build system to latest
* use new `updateRecord`
* bump nim-libp2p-dht
* bump nimbus build system
* bumping deps
* update to latest dht
Support latest version of nim-ethers which relies on nim-eth.
NOTE: This commit points to PR #31 which is a branch of nim-ethers. That branch should probably be merged first, and this PR updated to point to the commit on main.
Make RequestId, SlotId, Nonce, PurcahseId distinct types.
Add/modify conversions to support the distinct type (ABI encoding/decoding, JSON encoding, REST decoding).
Update tests
- rename `ContractId` to `SlotId`
- add `RequestId`, `PurchaseId`, `Nonce` types as aliases of `array[32, byte]`
- rename `Proving.contracts` to `Proving.slots`
- change signatures of `isSlotCancelled` and `isCancelled` to use `SlotId` and `RequestId` types, respectively.
- change all references to `RequestId`, `SlotId`, and `PurchaseId`
