Update SIP-12 with multiple resolutions & optimization

[hmalik88]

SIP-12 is updated to allow for multiple resolutions across different protocols. Snaps can also now identify the TLDs they support.

Note: In the future, the protocol string type will be further narrowed to a CAIP resolution protocol identifier. See ChainAgnostic/CAIPs#253

@hmalik88 We've put this in the backlog for now. Please update the group on the status when you return. Thank you!

@kenhkan this needs further review, I responded to Frederik's comments.

Hey, a DM from another MMer reminded me that I owe you review over on the CASA side! Is work continuing on this? where can i be helpful?

Quick question: how does this work for SUBDOMAINS? could sismo.eth be an entry in the TLD array, or are . characters excluded from it? Just wondering because I remember during peak ENS excitement days there were all these subdomain/sublease schemes...

Hmm to get a subdomain working you can technically do sismo.eth as a scheme in the schemes array!

I've paused work on the CAIP, I have to re-evaluate it's need in the future (domain lookup w/o that spec is fine in MM and I don't think anyone else in the space is thinking about this problem in depth yet 😄)
