I think we're long overdue for a Channel type in our data crate. We're exposing a ton of the complexities of parsing / dealing w/ channel prefix vs names across the codebase instead of encapsulating it within a channel module / type. We can then move this logic to an Ord implementation and because Channel will already have prefixes parsed out, the implementation can be much simpler.

I'm not sure we should block this work on it as it'd be a much bigger refactor, but I think it'd be really nice to clean this up along w/ dealing w/ channels and "targets" (channel vs query "nick") throughout the codebase instead of just String like we've been doing.

one issue is that Ord (as in hashmap) and Ord as in channel sorting are (and should be!) different

we really want a locale-dependent sort on channels and i don't think this is suitable for Ord, which the BTreeMap is based on (for an example of this see my gamja PR)

I wasn't entirely sure on how to rectify this so i decided to not work on it in this PR... so maybe we should push it to another PR?
