Update coord criteria regex so that X prefixes or _ infixes don't break it

[jthielen]

Description Of Changes

Over the course of working on xarray-contrib/xwrf#14 and recieving feedback on it, bugs arose in some edge cases of the regex coordinate criteria, particularly, XTIME got interpretted as an x axis coordinate (which is very much not right). To resolve this, I tightened the criteria with start and end matching, and then filled in what I'd otherwise expect to be allowed in between. WRF/xwrf-motivated test dimension names have also been added.

Codespell is failing on pres (instead of press), which seems to be causing the required linting CI to fail. What approach should I use to override codespell for this?

[dcamron]

That line was previous excluded via the .codespellignore file, so you should be able to just update that line to match your change (must be exact!).

[dopplershift]

Looks good, modulo fixing for codespell (as @dcamron correctly stated how to suppress).

[jthielen]

.codespellignore has been updated as suggested, and it looks like lint CI is now passing!
