…. The C API and command line tool
are updated to support the new function.

Changes are:

1. Change how operating points are computed to mirror eval (i.e. operating points are added only if both the true positive AND false positive count changes). This fixes a bug where successive operating points could have the same FAR, which caused nan results in the output.

2. Change the optional pdf argument to a CSV argument (again mirroring eval) so that results are written as CSVs and can be combined to show multiple results on the same plot

…in the templates metadata
roi.cpp copyOnCrop=True is now the default
rotate.cpp rotates a mat by 90 intervals
extractvaluefromLlist.cpp extracts a single value from a list in metadata and saves it in a new key
majorityvoting.cpp Calculates which class has the highest scores when given a list of scores for each class
scorelevelfusion.cpp Fuses the scores together for each class when given a list of scores for each class

…truth boxes that are beyond the specified thresholds
