Patch hmr agora

[dldaisy]

Training agora directly with current hmr pipeline would fail, since hmr didn't recenter 3d joints to 0 for agora dataset. Meanwhile, since smpl kid have 11 dimensions, which is not compatible to smpl neutral/male/female, I think it's better to discard kids data in agora dataset rather than truncating the first 10 dimensions to unify data as done in current code.

Hi @dldaisy, thanks for your inputs!

I did not adopt this 34b047f as it would affect the training for models which uses H36M and MPI-INF-3DHP datasets asleft_hip_extra and right_hip_extra is used to calculate the gt_pelvis. To fix the bug in AGORA, I've centered the 3D keypoints according to the pelvis and added left_hip_extra and right_hip_extra in #202.

I've incorporated your suggestion to remove kid annotations in #202.

Hope this helps, thanks!
