feat(auto_export): experimenting with the insane workarounds needed to get access to standard gltf exporter settings

* got a basic working version that runs the standard exporter with some overrides,
deletes the temporary exported gltf file, extracts the scene level settings etc
 * convoluted as hell , but still better than the alternatives

This is a workaround needed because of the way the settings are stored , perhaps there is a better way to deal with it ? ie by calling the AutoExportGLTF operator from the auto_export function ?
