RCAL-701: Level 3 Mosaic Update

[PaulHuwe]

Resolves RCAL-701

Closes #

This PR updates the contents of the WFI_Mosaic datamodel, maker utilities, and tests to a more streamlined metadata design for level 3 products.

This update is expected to require new RomanCAL regression test files, so there will be no jenkins link below. There is a RomanCAL ticket for the code dependency changes: spacetelescope/romancal#1057

Checklist

• Added entry in CHANGES.rst under the corresponding subsection
• updated relevant tests
• updated relevant documentation
• Passed romancal regression testing on Jenkins / PLWishMaster. Link: https://plwishmaster.stsci.edu:8081/job/RT/job/Roman-Developers-Pull-Requests/580/

FYI, this all looks good to me, but let's not merge until seeing what needs to happen in romancal. Thanks!

[PaulHuwe]

The old dependency failure is expected, due to the astropy Table tag version.

[braingram]

Any reason to not bump asdf-astropy>=0.5.0 to fix the oldestdeps?

[schlafly]

This looks good to me. I am leery of actually using the append_individual_image_meta stuff until we have actually tried running it on real images; I worry about weird things in the metadata like ndarrays from source detection, etc.. But it's fine for the moment since we haven't actually turned that on in romancal, I think? Can you and @stscieisenhamer coordinate to merge these and get the L3 bits working with the new schema? Thank you!

LGTM, you don't need to change anything.

Just an observation: we usually we abbreviate association as asn so mosasn instead of mosass.
You did get a good laugh out of me.
