164 Add x-ray microservice

[troglodite2]

CL needs to be able to check PDFs for bad redactions. Rather than adding x-ray to CL we added a new microservice /utils/x-ray/pdf/ to do so

Two new unit tests were added which sends PDFs to be checked. The PDFs to check were pulled from the x-ray repo. The naming convention requires 'yes' for PDFs with bad redactions and "no" when they do not.

Fixes: #164

Huh. Doctor tests don't seem to run automatically. Want to take a look at how CL or bots.law runs tests and add them to this PR?

I'm not sure what is happening. I ran the .github/workflow/{test,lint}.yml actions and they reported no errors.
