Create the spatial index loader for a points node. The points
loader handles 3D datasets without spatial indices itself, so this
is the universal points entry point.
Note: the SceneLoader still owns monitor-connection — this factory
only constructs the loader, deliberately not the side-effect of
registering it with the data monitor.
