Pytest and flake8 config in `setup.cfg`

[nathanjmcdougall]

grimp/setup.cfg

Lines 1 to 7 in 7fc49c4

	[flake8]
	extend-ignore = E731, E203
	max-line-length = 100
	exclude = */migrations/*, tests/assets/*
	[tool:pytest]
	xfail_strict=true

I'm thinking that the flake8 config can be removed (superseded by Ruff), and the pytest config can be moved into pyproject.toml.

Yes good idea.
