Initial draft of GitHub Actions workflow. Probably needs some refinement but I think most of it is there already, just needs to be double checked (and confirmation that it works) before moving forward.

Merging #35 (aba445e) into master (9c15c96) will not change coverage. The diff coverage is n/a.

So far so good. I'm going to push with some minor changes that change the coverage to make sure the diff coverage report shows up when the coverage is actually changed in a PR.

Okay, I think this is doing all of the things I want it to do now. I added some changes to codecov.yml to add in the coverage delta table and the Coverage Diff table since those are pretty nice 'at a glance' metrics. I'll remove the unnecessary changes here and remove the draft status.

Alright, all tests are passing on the new CI and the coverage report looks good. Merging now.
