Finish adding mypy type checking

[nreinicke]

We've started adding type hints to the python wrapper of the app but haven't gotten full coverage. Add in any missing types and then we can activate the mypy check in our GitHub action.

I'll take this one. I don't get any errors from mypy after installing the type stubs for what's needed, but if I add --strict I see a bunch of errors:

After discussing with Nick, probably the check should be updated to add --strict since the goal of this is complete typing of the API. (I'm not sure if --install-types will make sense for the check or if that dependency on the type stubs should be declared explicitly somewhere)
