JP-4267: Add U4COORD and V4COORD to oifits model

[emolter]

Resolves JP-4267

Requires spacetelescope/stdatamodels#709 and some unit tests are expected to fail in the CI but pass on the regression tests pointed to that branch.

This PR adds u4coord and v4coord values to the oifits model q4 tables.
