js: Expose meshopt_spatialSortRemap as meshopt_encoder @ reorderPoints

Browse Source 
Similarly to reorderMesh, reorderPoints can improve spatial locality of
point clouds, which results in improved compression ratio when using
attribute encoder, and may also improve rendering performance by
improving rasterization locality.
