Set up packaging with setup.cfg and introduce linters

[eggplants]

I added and configured flake8 + black + isort + mypy to dev dependencies, pre-commit and CI.

And I moved package's metadata and configurations of linters from setup.py into setup.cfg.

I'm ready for review!

This is looking good. The lint test seems to be failing when I launch it. If you think this is only an issue within the PR context, I can merge and check then.

Sorry, fixed.

Looks like the linter is running now, but kicking up an error:

Looks like that fixed everything. Thanks!
