Fleshed out the "Optimize Mesh" options found in the mesh import UI
Gave a checkbox to every vertex attribute that can be compressed
Surfaced option to enable/disable Octahedral compression for
normal/tangent vectors
Also surfaces the vertex position compression option which previously
inaccessible because the defaults did not compress vertex positions
Supports all current importers (obj, fbx, collada, gltf)
