Merge pull request #187 from preservim/test

Add CI workflow to actually test-drive Vimux

This is fairly primitive, but it's a start. At least we will know if a PR makes some egregious error that makes basic functionality die. In the future we should probably write some small test scripts and verify the contents of panes with some sort of content capture for true unit regression testing, but a pass/fail grade that we don't explode is better than no testing.
