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.
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
- 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
- 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
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)
- 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
