DIR curve should be updated to PNIR vs. FPIR curve
According to the new standards, the Detection and Identification Rate curve (DIR) has been renamed by the ISO: https://www.iso.org/obp/ui/fr/#iso:std:iso-iec:19795:-1:ed-2:v1:en The two axes are now called False Positive Identification Rate (FPIR) and False Negative Identification rate (FNIR) = 1- True Positive Identification Rate (TPIR). I do not really know how the curve is now called -- the according part of the ISO document is only available after payment.
So, the first (and easiest) task is to rename the axes to FPIR and TPIR. Second, we should see if our implementation strictly follows the definition (which I believe is the case). Finally, sometimes the curve is plotted with logarithmical y-axis (the x-axis is always log), which only works if we plot FNIR instead of TPIR. It might be good to add both possibilities as flags.
