Pytest ini options in pyproject.toml

Raised in #368 by @rwb27

I see that this is the same as CI. I've mentioned elsewhere that I tend not to add the --cov argument, as it's in pyproject.toml. The relevant lines are:

[tool.pytest.ini_options]
addopts = [
    "--cov=labthings_fastapi",
    "--cov-report=term",
    "--cov-report=xml:coverage.xml",
    "--cov-report=html:htmlcov",
    "--cov-report=lcov",
]

I'd happily get rid of some of those if they're not needed, in particular I think the XML output requires a dependency and isn't used in CI? It would also be reasonable to disable HTML output by default. That was a stop-gap for me, before I realised the VSCode integration was much more useful.

We also now have --cov=src and --cov-report=json in that section

I think only the lcov and json are used in CI, so perhaps we skim this down to:

[tool.pytest.ini_options]
addopts = [
    "--cov=src",
    "--cov-report=lcov",
    "--cov-report=json",
]

That feels like an easy enough change.
