GltfLoaderPlugin : Add a Parameter to allow Gltf Nodes without name to be created

[K01603779]

Currently in the GLTFLoaderPlugin a node in a Gltf-Model that doesn't have a name is not created and added to the scene
https://github.com/xeokit/xeokit-sdk/blob/master/src/plugins/GLTFLoaderPlugin/GLTFLoaderPlugin.js#L348 :

if (!name) {
   return true; // Continue descending this node subtree
}

Would it be possible to add an optional parameter, that would allow one to create these nodes to have them in created e.g., with an sequential name, since would sometimes be needed to have a correct scene tree of the model displayed.
