Links to IRCv3.1 and IRCv3.2 are no longer available, IRCv3 WG no longer issues point releases

[johnmaguire]

These links in the README no longer link to IRCv3.1 and IRCv3.2 specifications: https://github.com/aatxe/irc/blame/develop/README.md#L15-L18

They now redirect here https://ircv3.net/irc/ which shows various IRCv3 extensions. Is there a list of which extensions the irc crate supports instead?

Welp, that's an unfortunate change. We don't have a compiled list anywhere (though I imagine just looking at the archived versions of the linked pages would be helpful in that respect). Just skimming the main list, I think we support the majority of the extensions there, including the deprecated METADATA extension.
