Produce stacked cutouts for each date in a KBMOD pile of results

[ColinOrionChandler]

In addition to the master cutout, we need one stack per day of images, for example we have 100 images from one night and 100 images from a night a month later.

Ideally, how would you want this to work in the context of the KBMOD flow?

Some specific questions:

1. Should this always be done on every run? Or is this just useful during certain debugging situations?
2. Is there an optimal way to break up the nights? Can we do something like call it a new day anytime there is a gap of >8 hours between two images?
3. Do we want to generate all stamps or just the one used for filtering?
