TDC

Features added in this MR:

• TDC modules for each Hitor line (BDAQ/USBPix, KC705 supports only sampling of Hitor signal, no trigger distance measurement possible)
• TDC raw data word analysis (details see code)
• Hitor calibration (calibrate TDC vs Delta Vcal)
  • new masking scheme: inject in one step into four pixels of different hitor lines
  • Arbitrary DeltaVcal range possible
  • output: TDC/TOT (mean and std) as 2D map (for each pixel) for each scan parameter, will be used for charge calibration
  • Test + fixtures (also check for TDC interpretation)

Things which will be added later:

• TDC gating
• Timewalkscan (SW + FW)
• Optional use_tdc parameter in e.g. source scan (needs restructure of config yaml, see #205 (closed))
