Commit Message

Add eth_call state overrides and eth_createAccessList support

- New :state_overrides option on Ethers.call/2 and Ethers.estimate_gas/2 to
  simulate against modified chain state (balances, nonces, code, storage slots)
- New Ethers.StateOverride module validating and encoding override sets into
  their JSON-RPC representation
- New Ethers.create_access_list/2 (+ bang variant) wrapping eth_createAccessList,
  returning the access list in the format transaction overrides accept so it can
  be fed straight back into send_transaction
- New optional RPC adapter callbacks (eth_call/4, eth_estimate_gas/4,
  eth_create_access_list/3) - custom adapters remain backwards compatible and
  get {:error, :state_overrides_not_supported} / {:error, :not_supported} when
  they do not implement them
