Add the ability to propagate the same photons multiple times on the
the GPU, and run the DAQ multiple times on the same photons in a
likelihood calculation.
Propagating the same photons in a warp speeds up propagation by a
factor of 3 (and we could do this even better if we wanted), and this
improves the statistics in a likelihood evaluation quite a bit.
Running the DAQ multiple times is also an inexpensive way to improve
the quality of the PDF estimates.
