This PR adds a new function to the Strings library that converts an address to its ASCII string hexadecimal representation. The main motivation is the reason that I've encountered already multiple projects that use a sophisticated tokenURI strategy, that concatenates multiple attributes - one of which is an address - into a string. An example:

return string(abi.encodePacked(_baseTokenURI, toString(creator), "-", tokenId.toString()));

PR Checklist

  • Tests

Thank you @pcaversaccio! I agree I can imagine this will be very handy for on-chain NFT metadata.

Maybe we say that the produced address is not checksummed.

@Amxx good point - I added the comment! Somehow the CI actions don't work on this PR?

@pcaversaccio It may have been a GitHub problem.
