Test framework

[themikejr]

This PR does the following:

• introduces the pytest framework
• adds base unit test suite for nodes, lowfat, and tsv
• a github action that will prevent pull requests from being merged if the tests fail

[themikejr]

There are currently two failing tests that ironically prevent this from being merged:

1. number of words in lowfat
2. number of words in macula_hebrew.tsv

Given that the missing words are a known issue (https://github.com/Clear-Bible/symphony-team/issues/207), I would suggest we either:

1) Update the expected word counts to match what is actually in the lowfat / TSVs (and then the "fix" for #207 would include updating the tests so they pass again with the new counts) 2) Mark them using the xfail marker; when we resolve #207, we can remove the marker

Thanks for the suggestions @jacobwegner. I went with the latter so that we don't lose the encoded expectation of the correct number of words.

I believe this is ready for review now.
