Add `recover_signer`

[fubuloubu]

Overview

It'd be nice to have a utility function to return the signer address of a message for verification purposes. Thankfully, eth-account exposes an easy method for signature verification that we can make even easier.

Specification

Add the following to src/ape/types/signatures.py:

def recover_signer(msg: SignableMessage, sig: MessageSignature) -> AddressType:
    return eth_account.Account.recover_message(msg.signable_message, signature=sig.encode_vrs())
