…. 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
