ADC offset calculation using data from pulser walkthrough runs, see:
https://elog.ph.ed.ac.uk/AIDA/603

Attachment 1,2: excel and text file with tabulated ADC offset values.
Attachment 3,4: 2D histogram pulser amplitute vs channel number (with gain matching applied) for validating the
calculation.

Note: Channel with ADC offset=0 means ADC offset could not be calculated properly due to poor resolution/low
statistic
