* Remove overloaded UInt256.fromJson
Rely instead on UInt256.fromJson from nim-serde, which deserializes an empty string for ?UInt256 into UInt256.none. Previously, empty strings were deserialized into 0.u256. BlockNumber was using this deserialization, and it appears that deserializing a missing block number from a TransactionReceipt into 0 might actually cause some issues when waiting on block confirmations.
* bump version of serde
* Remove "v" from version in `.nimble`
* Fix nimble serde version again ¯\_(ツ)_/¯
Updates hardhat and solidity
Uses personal_sign instead of eth_sign, because ethers.js also uses personal_sign, and eth_sign is now broken in hardhat (arguments are reversed).

* Add json de/serialization lib from codex to handle conversions
json-rpc now requires nim-json-serialization to convert types to/from json. Use the nim-json-serialization signatures to call the json serialization lib from nim-codex (should be moved to its own lib)
* Add ethers implementation for setMethodHandler
Was removed in json-rpc
* More json conversion updates
* Fix json_rpc.call returning JsonString instead of JsonNode
* Update exceptions
Use {.async: (raises: [...].} where needed
Annotate provider with {.push raises:[].}
Format signatures
* Start fixing tests (mainly conversion fixes)
* rename sender to `from`, update json error logging, add more conversions
* Refactor exceptions for providers and signers, fix more tests
- signer procs raise SignerError, provider procs raise ProviderError
- WalletError now inherits from SignerError
- move wallet module under signers
- create jsonrpo moudle under signers
- bump nim-json-rpc for null-handling fixes
- All jsonrpc provider tests passing, still need to fix others
* remove raises from async annotation for dynamic dispatch
- removes async: raises from getAddress and signTransaction because derived JsonRpcSigner methods were not being used when dynamically dispatched. Once `raises` was removed from the async annotation, the dynamic dispatch worked again. This is only the case for getAddress and signTransaction.
- add gcsafe annotation to wallet.provider so that it matches the base method
* Catch EstimateGasError before ProviderError
EstimateGasError is now a ProviderError (it is a SignerError, and SignerError is a ProviderError), so EstimateGasErrors were not being caught
* clean up - all tests passing
* support nim 2.0
* lock in chronos version
* Add serde options to the json util, along with tests
next step is to:
1. change back any ethers var names that were changed for serialization purposes, eg `from` and `type`
2. move the json util to its own lib
* bump json-rpc to 0.4.0 and fix test
* fix: specify raises for getAddress and sendTransaction
Fixes issue where getAddress and sendTransaction could not be found for MockSigner in tests. The problem was that the async: raises update had not been applied to the MockSigner.
* handle exceptions during jsonrpc init
There are too many exceptions to catch individually, including chronos raising CatchableError exceptions in await expansion. There are also many other errors captured inside of the new proc with CatchableError. Instead of making it more complicated and harder to read, I think sticking with excepting CatchableError inside of convertError is a sensible solution
* cleanup
* deserialize key defaults to serialize key
* Add more tests for OptIn/OptOut/Strict modes, fix logic
* use nim-serde instead of json util
Allows aliasing of de/serialized fields, so revert changes of sender to `from` and transactionType to `type`
* Move hash* shim to its own module
* address PR feedback
- add comments to hashes shim
- remove .catch from callback condition
- derive SignerError from EthersError instead of ProviderError. This allows Providers and Signers to be separate, as Ledger does it, to isolate functionality. Some signer functions now raise both ProviderError and SignerError
- Update reverts to check for SignerError
- Update ERC-20 method comment
* rename subscriptions.init > subscriptions.start
- async lock during nonce sequencing + gas estimation
- simplified cancelTransaction (still exported) such that the new transaction is populated using populateTransaction, so that all gas and fees are reset
- moved reverting contract function into its own testing helpers module, and refactored any tests to use it
- updated the test helper reverts to check EstimateGasErrors
- combine ensureNonceSequence into populateTransaction
Based on ethers.js's queryFilter, allows querying of past contract events, by querying the logs for a contract's event topic.
* queryFilter to query past logs
* Allow querying of past block log events
* Can query by block number or block hash
- `TransactionReceipt.blockHash` is optional
- Block.number is optional (in case node doesn’t return this in the event)
- Refactor confirmations waiting such that there is no polling for a receipt at the start
- Make BlockHandler and SubscriptionHandler async
- change casing of constants
- change return type checking of contract method to check for `Confirmable` instead of `?TransactionRepsonse`
- Reduce miner sleep to 10ms
- Change `wait` and `Waitable` to `confirm` and `Confirmable` to avoid conflict with chrono’s `.wait`.
- Update params on `.confirm` so that the compiler can restrict values of the `int` to `Positive` and `Natural`.
- Add `Block` and `TransactionReceipt` conversion tests to test for missing block number and block hash.
- Add tests for confirmation calculations and determining if a tx has been mined from its receipt.
- Assume that blockNumber returned from node will be null or empty string, in which case we can parse as 0 and test for that condition.
Allow waiting for a specified number of confirmations for contract transactions.
This change only requires an optional TransactionResponse return type to be added to the contract function. This allows the transaction hash to be passed to `.wait`.
For example, previously the `mint` method looked like this without a return value:
```
method mint(token: TestToken, holder: Address, amount: UInt256) {.base, contract.}
```
it still works without a return value, but if we want to wait for a 3 confirmations, we can now define it like this:
```
method mint(token: TestToken, holder: Address, amount: UInt256): ?TransactionResponse {.base, contract.}
```
and use like this:
```
let receipt = await token.connect(signer0)
.mint(accounts[1], 100.u256)
.wait(3) # wait for 3 confirmations
```
Allows specified number of transaction confirmations to be awaited before a transaction is considered finalised. Polls for a transaction receipt then listens for new blocks and calculates the number of blocks between the receipt and the new block.
Notes
1. Only works with websockets currently
2. Replaced transaction not supported yet
Ensures that even when a call to the ethereum node to
unsubscribe fails, it will release the memory associated
with the subscription, including the subscription handler
closure.
