Ping Tag Support

[TheDiscordian]

I think the Protocol interface should support ping tags by default to make forming and parsing responses easier. I think methods could look like these:

• GetPingTags(msg string) (string, [][2]string) - I'm thinking this could return the original message with tags replaced by UUIDs, then an ordered list of [uuid,displayName] matches for easy parsing. This could make parsing tags much easier, and universal. I'm not sure how UUIDs could be typed this way, but they should be mostly safe due to loads of strict typing everywhere else.
• MakePingTag(uuid UUID, displayName string) string

Instead of GetPingTags, maybe messages should just have a method for dumping post-pingtag processing? Or both? Or maybe just go right to the extreme and replace text dumping with a result akin to GetPingTags? So many options : /.

MakePingTag would be extremely useful.

Investigate how the discordgo plugin does this.

Bluesky is quite elegant with how they handle pings (slice of ranges), we could more-or-less adopt their standard.
