added scattered light, light saber anomalies for niriss

[rcooper295]

Addresses issue #1128, adding NIRISS-specific anomalies to constants.py

Requires NIRISS anomaly database reset.

Hey @rcooper295 thanks for the updates. Would you mind linking us to documentation on what light and light saber anomalies are? I would like to start collecting documents to eventually add links for examples and descriptions to our anomaly pages.

I made a new branch yesterday to start collecting images of anomalies, and I grabbed a light saber example.

Here is the JDox page with info about the light saber: https://jwst-docs.stsci.edu/jwst-near-infrared-imager-and-slitless-spectrograph/niriss-features-and-caveats#NIRISSFeaturesandCaveats-Lightsaber
and the scattered light: https://jwst-docs.stsci.edu/jwst-near-infrared-imager-and-slitless-spectrograph/niriss-features-and-caveats#NIRISSFeaturesandCaveats-Straylight

Steph also identified a couple of examples of these on JWQL, so I can share those exposure numbers with you if you want more examples.
Thanks for the merge!
