Issue DM-2434: Draw simulated PSFs from a library of on-disk files
Modify the simulation code to draw PSFs at random from a library of on-disk files (whose format and on-disk layout should be specified here). The PSFs chosen should be deterministic via a random number generator seed specified via config. This is one of several issues that together will replace DM-1132 (which was just a planning stand-in for these more detailed issues).
