Gh action to lint python and auto fix issues

[mohitdmak]

Hello @jakebeal , this PR hopefully fixes #68

• This currently uses flake8 and black linters.
• In case of style issues, a new commit is automatically made fixing changes recommended by black

Do we need to proceed with recommended code styles by these linters, or:

• Lint code by customizing lint rules?

Thank you for the contribution!

Three thoughts regarding your question:

1. I notice that flake8 is declaring a failure, but the code is passing in the action?
2. It looks to me like it's being a little bit heavy-handed on the formatting --- can we dial it down to be less sensitive (e.g., just PEP8 compliance)?
3. I'm not sure I'm comfortable doing auto-reformatting. I'd prefer to have it declare PEP8 violation errors and have the person pushing responsible for fixing.

Regarding

1. Actually, gh actions don't support auto commits or annotations on PRs from a forked repo, it is referenced by the creator of this action here: link . I have tried the workaround mentioned here by triggering the actions on pull_request_target events which should allow annotations on non-local PRs.
2. This should be possible, would look into it.
3. Sure, I disabled the auto committing, and once you run the workflows we can test if the annotations have started working here.

I guess I don't know what you mean by an annotation --- I thought we would see a failure due to linting errors.
