Add images that trigger the CR flag to badexp file

I ran through the -photom files looking for images with a lot of stars marked as cosmic rays.  The above images are the worst cases, with more than 10% of stars marked as CRs and more than 5000 stars total.  Running through these, most are triggered by blobby/donut-like PSFs.  This PR adds those to the badexp list.  It looks like one could find ~10x more such images if one did CR-frac > 0.01 and nstar > 100,
