Build a CI/CD testing pipeline

[KennethGrace]

We need to add files to a tests directory and setup some GitHub actions to test our code. Beyond untitests for the basic operation of our functions, this should be a collection of unit tests that run every script in the scripts' directory and confirm the output matches our expectations. For this we will need some clean sample data.

I've created some clean sample VOSS tech files in the tests/data directory for use in unit testing. We now have a simple expected state to test against.
