Asset idea: UsdGeom Meshes and Subdivs

[crydalch]

While many assets already exercise meshes by default, it might be nice to have a special test that exercises the various properties of meshes.

• Subdivision surfaces
• Subdiv creases
• Right- and Left-handed orientation
• Geomsubsets

I have a simple asset I could contribute for these cases.

I would be most interested in Geomsubsets and how to use them with instancable meshes.

@PixelPartner this might be a good starting point for that -- https://github.com/PixarAnimationStudios/OpenUSD/tree/release/pxr/usdImaging/usdImagingGL/testenv/testUsdImagingGLGeomSubsets
