Warnings are raised by the test suite

[WilliamJamieson]

When I run the tests in roman_datamodels locally, I am currently getting 44 warnings. Ideally, we should address and correct these warnings as they appear in the suite, either by ignoring them (if we feel they are irrelevant) or by resolving the cause of the waning itself.

The warning report I am currently getting is:
