Here I'm adding a new helper function that extracts the revert reason of
a contract call. Unfortunately, this aspect of the API is underspecified.
See these spec issues for more detail:
- https://github.com/ethereum/execution-apis/issues/232
- https://github.com/ethereum/execution-apis/issues/463
- https://github.com/ethereum/execution-apis/issues/523
The function added here only works with Geth-like servers that return
error code `3`. We will not be able to support all possible servers.
However, if there is a specific server implementation that makes it
possible to extract the same info, we could add it in the same function
as well.
