Strobe delay analysis for Stars

@elebouli

Implementation and analysis for strobe delay scan.

StarStrobeDelayFitter is a AnalysisAlgorithm which takes in occupancy maps and does the following:

1. for each channel, make a histogram of occupancy vs strobe delay
2. fit the rising and falling edge of the histogram from 1 using two s-curves
3. find the max rising edge and min falling edge among all channels within a chip
4. define the optimal strobe delay setting to be 57% between max rising and min falling

Results are dumped into JsonData files as well as in the following plots:

• occupancy vs strobe delay for individual channels (if option dumpDebugSDPlots is true)
• distributions of rising and falling edge for all channels
• 2D histograms of occupancy vs strobe delay vs channel number, separated by chip and by row

The config std_strobeDelayScan_fileInputs_template.json can be used to run the analysis on occupancy maps from a previous scan.
