Add actual report tests with data to CI/CD

[krowvin]

Running the pytest -v and checking the forms for #26 I realized it does not actually appear to be generating output with data.

It does check conversions, size compares, etc. Which is important.

Consider another CI/CD pipeline that tests various reports from districts so that as we make changes we can confirm it will run on district production reports.

Thoughts:

• Picks specific dates in time in the past so that the expected output can match what is requested
• Add a #FORMURL method that does a fetch for a plaintext form elsewhere (another github repo possibly) and runs from that form
  On second thought, decoupling the DEF from the FORM this much is probably a bad idea
