Make some DUT functions more efficient using std::count_if.
Make them aware of several ROCs.
Rework RocSetMask and PixelSetMask functions to also set the trim information
delivered by the DUT.
Add new MaskAndTrim() routine to the API as central point for all (un)masking and
trimming operations. This should be called before any test (now done in expandLoop)
and when starting up a new DAQ session (to be done).
Minor fixes in the DEBUG printout and typecast warnings.
Fix bug in testPixel(): the mask bit is inverted w.r.t. to the enable bit.
Rework maskAllPixels and testAllPixels functions to be aware of more than one ROC.
Default is still to do the same thing on every ROC.
