Message:

Add recipe value FOOTPRINT_SET_NANS_TO_ZERO which when set sets NAN pixels to zero
in the image that is used to Cull Peaks. Set to false for now.
Also add recipe value PSPHOT.CR.MAX.WINDOW default 50) which limits the size
of the region checked for cosmic rays. Previously the entire footprint was
checked which performed horribly with really large footprints.
