Migrate flake8, isort, black rules to ruff

[weiji14]

Translating the previous flake8 rules in setup.cfg to ruff rules in pyproject.toml. Original rules were set in #15.

The following ruff lint rules are set:

• B - flake8-bugbear
• C4 -flake8-comprehensions
• C90 - mccabe
• E - pycodestyle
• F - pyflakes
• I - isort
• SIM - flake8-simplify
• W - pycodestyle warnings

Notes:

• Did not keep any of the ignored rules (E203,E266,E501,W503,E722,E402,C901,E731) since none of them were triggered
• Dropped the deprecated flake8-mypy (T4) rule.

Part of effort at #47 to remove the setup.cfg file.

i would replace isort and black too while you're at it.

Cool, thanks for the tips @dcherian. There's a few more linter stuff we can move to ruff, but that can wait. I'll merge this in now and combine it into #48.
