Need a DQM analyzer for new digi collections

[bryngemark]

The priority on this potentially increased now that there will very soon be an automatic validation procedure for PRs, involving running the DQM plots and comparing them to a set of reference plots created upon making stable releases.

I think the old digi plots still work for RecHits, since they have the same set of variables. It's mostly a matter of also making histograms of ADC, TDC and CID values for the QIE digis. And any other plots that could be helpful for checking that nothing is broken, of course.

Ok. I think we can also add a few more histograms for bar IDs and perhaps the linearized charges if required.
