📝 Summary

Adds two more unit tests for flashbots.ParseSignature using two signatures generated via MetaMask and cast.

⛱ Motivation and Context

I realized that the existing TestParseSignature test uses the crypto package to generate the signatures, and since this is the same package we use internally to verify the signatures it was possible that we had a bug in both our uses for generation and validation of the package. So as an extra sanity check I generated two additional signatures using MetaMask and cast to confirm that our signature verification code works across multiple signature implementations.

I actually wasn't aware of this nice extra feature of etherscan where signatures can be published that also offers a nice UI for prompting your wallet to generate a signature: https://etherscan.io/verifiedSignatures#
