Add AI create channel tests

[zhindes]

• This contribution adheres to CONTRIBUTING.md.

What does this Pull Request accomplish?

This adds a test per non-TEDS AI create channel method to validate that they can successfully be used. There is a small amount of functional validation that parameters are properly being passed through the layers of Python and underlying driver API.

Why should this Pull Request be merged?

This will give us confidence that we haven't broken anything as we refactor parts of the Python and driver stack. This also helped uncover some usability issues with the Python API:

• Default argument values for bridge create channel functions are unusable #482
• add_ai_rosette_strain_gage_chan parameter rosette_meas_types has the wrong type #483

What testing has been done?

All existing unit tests pass, skip,or xfail as before. New unit tests:
