Add test coverage report/badges

**Is your feature request related to a problem? Please describe.**

We should publish badges for the state of the build

**Describe the solution you'd like**
Badges on the front page of the repo

Start by reviewing the repository's existing build and CI configuration to find where test execution and status reporting are defined. Confirm which build-state and coverage badges are required, where they should appear on the repository front page, and verify that the published badges reflect the completed checks.
