EIP-838 Error Codes

[TomiOhl]

Expected behavior

It would be nice to be able to get the new, custom error codes with their arguments, introduced in Solidity 0.8.4.
Ethers.js already supports them: https://github.com/shapeshift/ethers.js/blob/master/packages/tests/src.ts/test-contract-interface.ts#L636

Actual behavior

If I try to catch the error as in the link above, I get the following error message:
Error: Returned error: VM Exception while processing transaction: revert
Error code, error name, etc. are all undefined

Steps to reproduce the behavior

1. Send a transaction to a contract that will revert with errors
2. Try to catch the error

Environment

Web3.js v1.5.1
Node v12.18.4
elementary OS 5.1.7

This will be addressed in the 4.x rewrite.

@philknows Is there a timeline for that? 🙂

Still important. OpenZeppelin Contracts is blocked from adopting custom errors until Web3.js supports them.
