GLTF Model Update

The GLTF-specific modelUpdate attribute is an object with child component names as keys. The top-level keys are the names of the child components to be updated. The values of each are nested position and rotation attributes to set as new values, respectively. Either position or rotation can be omitted if unchanged.
