Could be nice to load ply file

[haixuanTao]

It could be nice to load ply file as it might be common within the Python ecosystem.

I'm currenlty getting the following error:

Failed to decode message in "/Users/xaviertao/Downloads/so100/SO_5DOF_ARM100_8j/meshes/original.urdf": lz4 error: provided output is too small for the decompressed data, actual 260018, expected 260141

and

Failed to decode message in "/Users/xaviertao/Downloads/so100/SO_5DOF_ARM100_8j/meshes/original.urdf": Failed to read: failed to fill whole buffer

The file in question

meshes.zip
