enable more pylint

[wdpypere]

These are the main pylint tests which flag "old school" coding style from before python 3.6.

• I'm a bit hesitant to enable consider-using-fstring because it's a lot. I cleaned out a lot of projects already but still.
• super-with-arguments: was for python 2
• useless-object-inheritance: same, no need to add it anymore
• unidiomatic-typecheck: use isinstance(var, type) instead of if type(var) == type
• unnecessary-pass: if an empty function or class has a docstring, a pass is not needed.

This PR will fail it's own tests, needs #234
