Subject: [PATCH] Publish coverage on coveralls in gh workflow (WIP)

TODO:
Needs more troubleshooting:
- Official coveralls action does not seem to work well for Python
https://github.com/coverallsapp/github-action/issues/4
https://github.com/coverallsapp/github-action/issues/30
- Official coveralls cli triggers 500 on coveralls.io
- Inofficial coveralls action seems to correctly talk to the API
  but has issues finding the coverage data in the tests folder,
  or the corresponding code.
