Mscoco preprocessing flipping

[achigeor]

First of all thanks for the great repo!

In pose/datasets/mscoco.py, when the flipping happens, there is
pts = shufflelr(pts, width=img.size(2), dataset='mpii').

Does the flipping / mscoco training script work, or one should implement the matchedParts for mscoco?

Thanks!

Do you plan to federate multi-datasets training hg-net?

@achigeor Sorry I didn't check the correctness of this part. Did you get correct results or not?
