Add code coverage calculation to pre-commit stages

[delucchi-cmu]

I'm bummed when everything in pre-commit passes locally, then the github workflow lets me know that there's one new line that doesn't have test coverage.

Always aiming for 100% is a high bar, but even a warning that you're reducing coverage would be great!

It would be nice if we could output the total coverage during the pre-commit step. This would give a heads up to let the user know that the github workflow might fail.

We're already calculating the code coverage amounts, so this would be a matter of twiddling with the output/verbosity options to get something useful. The best I've come up with is below, and is basically using the pytest command $ python -m pytest -qq --cov=./src --cov-report=term-missing:skip-covered

Build documentation with Sphinx..........................................Passed

I like it:

• will show up every time you run pre-commit, even if the tests pass
• will show the line numbers of uncovered lines, and suppress all other text
• the individual tests that are passing are shown only as individual dots.

I don't like it:

• I can't get the dots to go away, but keep the coverage summary
