Proper Raw Data Interpreation and TDC feature for ITkPix

This MR adds:

• Proper event building for ITkPix (only using TLU words, tag-based event building will be implemented later)
• TDC feature for ITkPix (Hitor Calibration + TDC analysis)
• Bug fixes for TDC analysis
• Fix calculation of hitor calibration histograms
• Separation of chip specific analysises
• Add PToT and PToA analysis:
  • Can be enabled, as TDC, with analyze_ptot from testbench.yaml. Default is False
  • As for TDC feature, in case of analyze_ptot = True additional hit columns ptot and ptoa are added. The tot column in that case will be 0, since it does not exist in this mode.
  • Manually added analyze_ptot = True to all scans which use the ptot feature
  • Plotting: if ptot feature is used do not plot tot map, instead plot ptot and ptoa map
• More unit tests:
  • Test chunked analysis of hitor calibration
  • Test Ptot analog scan (including chunking)
  • Test ptot hitor calibration (including chunking)

Fixes #388 (closed)

Todos

• Write TLU words for every scan if ITkPix is used (needed for event building)
• remove _ptot scans, add option to use ptot as chip parameter (change configure step, change masking, add ptot table) (later, see #395 (closed) )
• Decrease tot_hist to 512 (1024 consumes to much RAM-memory and leads to MemoryErrors)
• Small unit test for ITKpix event building (check for missing tags)
