We should use a strict black standards?

PySyft's automated code standards can be found in the Github action for testing and the flake8 config. We enforce:

• No syntax errors or undefined names
• Naming that conforms with PEP8
• Code formatting with Black
• A variety of flake8 style rules
• 95% code coverage from tests (and 100% coverage of the tests themselves)
• Minimum ~50% docstring coverage
• No medium or high severity security issues from Bandit (low severity issues are things like "use of assert", which would be more a pain to get rid of than live with)

Thoughts on isort?
PySyft has a defined import style in the contributing doc, but it's not enforced AFAIK
