Interest in Expanding CI to test on macOS?

[j9ac9k]

Hello beets community,

I was recently working on a (very small) PR, and when I ran the test suite, it blew up due to an error on the test collection stage. I submitted another PR to address that issue, but I noticed that there is no macOS based CI test runner. Would that be something that would be wanted?

I'd be happy to work on a PR for that, but figured I would ask before I put in the effort.

Thanks
