I've tested this with in-flight NIRISS grism observations and a patched wfss_contam step. It all seems to be working properly. So I would be OK with merging this once my review questions have been answered.

I addressed the comments and enabled previously xfailed tests. Swara tested with this PR and hit the error in the contamination step.

Whoops - you've got 1 little flake8 issue.

Did a full regression test ever get run against this PR branch? A couple of us tested it on NIRISS WFSS processing only, which seemed to run OK, but never a full regtest.
