Make initial pedestal estimate non-integral
I noticed that the pedestals in protoDUNE RawDigits were always integral. My understanding is that the decoder was returning (for each channel) the ADC code where the mean value fell. On my request, Tom modified that code so that it now returns a non-integral value as though the counts in each bin were uniformly spread.
I see the pedestal values in RawDigit are now non-integral.

I attach plots showing the event-to-event variation (RMS for 50 events) of the pedestals with the old and new code. There is a decrease in the variation with the new code.
