Q3 2022 repository standardization (#25)

Standardizes this repository per the module template as of Q3 2022. All changes are copied over directly from the template, except for the tests, which have been rewritten. A couple of notes:
- I didn't bother rewriting the tests for JSON-RPC notifications, as that functionality will be implemented in a completely different manner in #24 has been merged.
- CI has been switched from CircleCI to GitHub Actions.
