Reorg CI + project

[icweaver]

What's changed

• switch to [workspace]
• use ParallelTestRunner
• refactor tests using reusable workflow

A few things I like:

• The status of compat tests on the release and dev versions of our packages can now be seen as individual badges on the README

• Related to this, we can now run these tests at different frequencies if we want (e.g., release tested once a week, dev once a day)

Things to consider

@cgarling brought up a great point about wanting to avoid increasing the maintenance burden that would have been introduced if we went with splitting out testing on stable and pre-release versions of Julia.

In this similar vein, I decided that splitting out testing the compatibility of our released and development versions of our JuliaAstro packages (i.e., master/main) is still warranted because we really do want to have both of those bits information easily accessible. My hope is that introducing the reusable github action workflow mitigates the maintenance burden that this would introduce

TBH I'm not very familiar with how this repo works so some of this is a little beyond me but I don't see any significant issues. Having the reusable parts in CI.yml that is called by CI_dev and CI_release seems like a good compromise.

Do the tests pass if you run on Julia 1.11?

That's a failing on my part, I should really flesh out the developer docs some more. Saving a to-do here for that #177

ooh, thank you for reminding me to update the versions we test on. Will follow up

• Update: Should be in now. bump Julia versions #178. There's currently some duplication with 1 == pre == v1.12 rn, but I figured having this as a set it and forget it setting with pre is preferable to manually needing to go in an update things when v1.13 comes out

Cool, looks like things are passing on Julia v10 and v11 on the dev versions of our packages. I'm liking the extra granularity we are getting now!
