Probably wrong encoding on big-endian computers

[kylebarron]

I often dump the bytes of a numpy array to a buffer for fast writing to file

quantized-mesh-encoder/quantized_mesh_encoder/encode.py

Line 144 in efd52a2

f.write(u_zz.tobytes())

This probably uses system endianness. Since quantized mesh files must be little-endian, presumably files written on big-endian computers would be incorrect.

Look at the Numpy byte-swapping docs for a fix

I think I'll set this as low-priority and only fix if someone raises an issue.
