Some first analysis of building events to look for implants and decays

Using both DISC and slow comparator values for time-stamp (whatever is available). Clearly there are some ADC
hits with a very early value for their corresponding time-stamp, that result in negative or very large dTS
values. Probably safer to use only ADC data for now (it's likely the simple algorithm used to correlate
discriminator hits and ADC hits can not cope with current conditions of ADC hits >> DISC hits):

Comparing analysis of file R51_3 for the two conditions: using the Fast discriminator data when available for
low energy range, or using only the time-stamp from the ADC hits.

The first two figures (time_stamp_dist_disc.png, XY_implant_disc_R51.png) are for including DISC hits as
time-stamp for event building: some have much smaller values than corresponding ADC hits, so the event is cut
short and we see a small number of identified implants.

Second set of plots is the same data but using only the timestamp for the slow comparator of the low energy
range. The number of identified events is much higher (compare 'Integral' value of the stats box).
