Thanks for picking this up @wolever !

A few things:

• Having both tox and github actions seems redundant.
• ~Were you not insterested in the linting and security checks? black, isort, flake8, mypy, security and bandit.
  I find these to be easy, low-hanging fruit procedures that bring in some benefits.~ Wait, I was looking at a commit, not the whole PR, yeah these are included, cool.

Side note: Some tests were marked as 'fix' b/c they're failing on my machine, which is Windows. I believe there's some encoding that adds \r\n instead of simply \n and tests were failing b/c of that. I was in the process of changing encoding, but not sure it's required..
