the PCK and AUC for MPI-INF-3DHP in PoseFormerV2

[JihuaPeng]

First, thanks for your greatest work of PoseFormerV2. I checked your code and found that when evaluating the mpii dataset, the calculation of the two metrics pck and auc is not defined. May I know how to calculate the pck and auc for mpiinf-3dhp? Thanks a lot!
