Add coverage config

[cbrnr]

Move .coveragerc to pyproject.toml and try to automatically run it with pytest.

[cbrnr]

Hmmm, pytest runs fine locally, I don't know why it's failing here (apparently, pytest-cov does not get installed?). Any idea @larsoner?

You'll need to add pytest-cov to

sleepecg/pyproject.toml

Line 78 in 94e8390

test-requires = "pytest"

From looking at lost of tracebacks on CIs and locally I'd recommend a couple more options we have in MNE-Python

Suggested change

	addopts = "--cov"
	addopts = "--cov=sleepecg -rfEXs --cov-report= --tb=short"

some of which could then be removed from

sleepecg/.github/workflows/cibuildwheel.yml

Line 98 in 94e8390

- run: pytest -rfEXs --cov=sleepecg --cov-report=xml --tb=short --cov-branch --color=yes $PYTEST_EXTRA tests/
