There were two bugs that are now fixed:

  - MakeCatalog: In a grown clump label image, the detections that
    have one or no clumps are fully filled. So there is no river
    pixels for them. I had not corrected the clump S/N calculations in
    MakeCatalog also consider this. Now this issue is corrected.

  - MakeCatalog: Although brightness was correctly calculated, in the
    final printing, it would be divided by the area! It is now fixed.

  - NoiseChisel: When finding the S/N quantile for clumps, it was
    mistakenly using the detection S/N quantile for both clumps and
    detections! Now it uses the correct value. Until now, these two
    were always the same, so I hadn't noticed this!
