AnalysisDUT: add histograms + change binning + remove Units::convert()
This MR contains the following changes:
- changed binning of all residual histograms, +/-0.2mm --> +/-500um (i.e. mm -> um and extended range)
- added histograms showing the cluster width and the cluster charge vs the row
- remove Units::convert() and replace by simple multiplication (is much faster)
