General naming consistencies -- fix + document + ensure best practices moving forward:

[elijahbenizzy]

Is your feature request related to a problem? Please describe. Too early in the library to have these -- we need to keep backwards compatibility but want to make it consistent/easy to reason about.

Specifically:

1. a_<plugin> versus plugin (done to distinctify async)
   • When should/should these ever live together?
   • Should we have a separate aio package? (or a or async (which isn't allowed)
2. b_<plugin> versus
   • Some have these and some don't (integrations.b_aiosqlite, etc...)
   • Confusing with a_ (a implies async, b implies burr, a_b implies async Burr I suppose?)
   • Done initially to disambiguate import names, although not consistently
3. plugin -> package extension name configuration
   • No clear mapping here
   • Makes it really hard to understand what needs to be installed
   • Maybe we have live checks -- should probably consistently be using this tool

Describe the solution you'd like

1. Come up with best practices
2. Document/ensure them, make any migrations needed
3. Figure out how to keep it consistent in the future (open-ended)

Describe alternatives you've considered Chaos :)
