PixelHistogram (#317)

Multi threaded filling of per pixel histograms for example for detector calibration

1. PixelHistogram - Generic variant expects already pedestal subtracted
data
2. PedestalTrackingHistogram - Terrible name, useful class. Keeps it's
own pedestal and does conversion and pedestal tracking in the worker
threads.
