[Halld-offline] too many photons reconstructed in b1pi

[Will Levine]

I think this issue is just due to the way the script is written. These
histograms are only filled if an "X" can be reconstructed, that is, if
four charged pions and two photons are reconstructed. So when Simon
made a change that increased the number of pions reconstructed, it
looks like the number of photons increases, but in fact the number of
reconstructed photons per reconstructed X remains almost constant.
Indeed there are too many photons reconstructed but this is not a new
problem.
