Add CI using pytest.

- Add the data files to make pytest run
- Remove the large file restrictions so that the data files (35M!) don't
  break pre-commit. This isn't ideal, but it's better than pulling
  them from elsewhere.
- Remove the windows-specific python stuff from requirements.txt
- Add a github workflow to set up everything and run pytest
