      Description

      When flats are very high flux the CR finding code thinks everything is a cosmic ray for some reason, though I've not dug into why that is. This causes problems, primarily that, because we routinely run the CR repair on things on the summit, that takes ages and wastes a lot of CPU and delays summit image processing.

      There are two fixes, and we should likely to both:

      1) Fix the actual saturation levels (for LATISS, for now, but everywhere eventually) so that things don't get flagged as SAT falsely, as I think that's happening here.
      2) Work out what is making this happen and fix that.

      This ticket is for both, though child tickets can be made to separate the issues as desired.

          I wonder if this is related to the issue I saw in DM-23680: running dark frames through CR rejection fails if the image isn't scaled by the darktime, even though that makes no sense.  This similarly doesn't make much sense, as I wouldn't think there'd be any pixel significantly different from any neighbors to look like a CR.
