updated requirements.txt

...based on pip freeze after pip install -r requirements.txt in a fresh venv

No feature added, just the inherent dependencies.

@aceisace I believe the test run config is broken, because the errors I got are not related to the requirements update:

Yes, you are right, I do know that some tests are currently failing and need some further investigation. But these aren't related to the PR. I'll take care of some of them shortly

[mrbwburns]

@aceisace do you want to wait for the tests to pass here or merge this without the checks?

merging #315 , hence this can be closed
