Include PyRight in CI

[tp832944]

Describe the feature that you would like.*

PyRight is a static type checker. Consider adding it to the dev tools for this repo.

https://github.com/microsoft/pyright

Alternatives: pylint, mypy

Why is this feature valuable to you?*

Check that type annotations are correct. Also that I can call functions correctly.

Describe alternatives you've considered

MyPy - See here for a detailed comparison.

Pylint - already on repo

Additional context

Initial investigations indicate that a significant amount of work will be required to ensure the codebase is compatible with pyright. A method of iterative compliance may be beneficial. I.E. when a developer edits a file they address pyright issues locally, but we do not check with pyright in the CI.
