Develop testing approach and workflow for Watcher

[cd-rite]

Possible avenue:
Develop a github actions workflow that can verify Watcher functions with latest version of the STIGMan API.
Create sets of .ckls (and/or xccdf) that, on import, will pass an appropriate subset of the Newman tests from the STIGMan repo.

unit tests are done, and parser/taskobject modules have their own tests. New features(api/auth error handling) will include testing for additional scenarios.
