The Datasmith GameThread + DirectLink initialization was trigerring some ensure which where sometimes not handled properly and could cause a crash.
We were not properly tagging Unreal's main thread and the dcc's main thread, causing those thread to compete for the main thread role.

Some DCC may close a 3d scene without closing the application, in that case they must be able to close the DirectLink source as well.
With the simplified DirectLink API (FDatasmithDirectLink) this was only achievable by creating a new scene that would override the existing one, which is not desirable in this case.
Our C# exporters can only use the simplified API at the moment and this seems like a common enough use-case to be added to FDatasmithDirectLink.

- Restoring previous FDatasmithSceneExporter::Reset() behavior but marking the function as deprecated.
It's previous usage of reseting the export progress without resetting the whole exporter state was discutable and confusing. If users want to fully reset the exporter they don't need the Reset() function.

rules of thumb:
- Actor transforms are in doubles
- mesh internal data are in floats, except UVs that are in doubles
- compiled 3dsmax, archicad, navisworks, revit, rhino, sketchup, solidworks
