allow ami_analyze step to run on cal files

[braingram]

This allows ami_analyze to run on cal files. A regression test is added (input and truth files will be added and a run started when the files are approved).

This is an alternative to #8448 and instead of using the generic DataModel converts the input ImageModel to a CubeModel before the dimension expansion.

Regression tests run at:
https://plwishmaster.stsci.edu:8081/job/RT/job/JWST-Developers-Pull-Requests/1411/
Showed 1 unrelated error in [stable-deps] test_filter_rotation – jwst.assign_wcs.tests.test_niriss which is also failing on main:
https://plwishmaster.stsci.edu:8081/job/RT/job/JWST/2869/testReport/junit/jwst.assign_wcs.tests/test_niriss/_stable_deps__test_filter_rotation/
The regtest added in this PR passed.

This modification looks good, I examined the outputs of the new regtest for 2D files and didn't notice anything obviously amiss. Thanks for doing this!
