reformat repo

[smribet]

This PR reformats the repo. I think it will make it easier to compare and maintain code.

[alex-rakowski]

What style did you format with?

[sezelt]

I am very much in favor of this change, and I think the overall sentiment at the dev meeting was in favor of this. @bsavitzky do you have any objections? If there are any spots where we really want some non-standard formatting we can mark it with #fmt: off/#fmt: on.

[alex-rakowski]

I'm also in favour. I think it would be worth adding a .pre-commit-config.yaml to have black autoformat on each commit for developers. Maybe that should be part of #502

[sezelt]

#502 is a step in that direction, but just as a check and not something that will force changes

[bsavitzky]

Sigh. Ok! Oh brave new world, with such uncompromising Python code formatters in it. [1][2]

@sezelt I approved PR #502. Unless you want to make additional edits, if you go ahead and un-draft it I/whoever can merge.

@alex-rakowski I don't want to have a .yaml action that modifies developer code just yet. It is, of course, not unreasonable, and I think perhaps we'll get there. For the moment, I'd prefer some stay on ceding control over minutiae of hand coding in favor of speed and determinism on fundamental grounds. [1] Yes, PR#502 defacto does that. Yes, this means you/we have to run black on our code ourselves. By hand. [laughs maniacally]

Let us continue discussion out in the world...

Anywho. Merged!
