autopep8 + clang-format

Ran autopep8 recursively on all python files with the setup.cfg in the repo:

autopep8 --in-place --aggressive --aggressive *.py -v

[pep8]
ignore = E121,E123,E126,E226,E24,E704,W503,W504
max-line-length = 199

We can combine this with a GitHub action to automatically check/correct PRs: https://github.com/marketplace/actions/autopep8
