Assemble Ground Truth light curve #142

We'll need to do a spatial association between our PhoSimSources and the DM CoaddSources, and then look up the photon counts for each PhoSimSource in each visit's PhoSim centroid file. These numbers of photons will then need converting into flux units, using the zero point for each visit image (the one that was used by DM during forced photometry). Where are these zero points stored? In the headers of the calibrated images that were the inputs to the ForcedPhotometry? In the ForcedSource catalog itself? (That would be nice).

Hey @jbkalmbach I'm not sure this a job for The Monitor, but do you want to look into this anyway?

@jbkalmbach @rbiswas4 We just decided that the spatial association of ForcedSources with PhoSim input sources by sky position is indeed a job for the Monitor, and Rahul is going to work on it over there. I guess to close this issue we'll need a Twinkles notebook that demonstrates the visualization of a Twinkles light curve including the reference, using the Monitor. Re-assigning to Rahul!

@SimonKrughoff just provided code in #217 - does this belong in the Monitor, @rbiswas4 ?
