Sockets on exported node groups need to be adjusted manually

[Fweeb]

When exporting nodes as a node group, there are no input or output sockets by default. You need to go into the exported file and manage the input and output sockets yourself.

This is a difficult one to resolve within the context of the exporter. Probably the best solution is to use backlinks. Then you can use the updated version of the Edit Linked Library add-on which now has support for jumping to linked node groups.

Otherwise, there will have to be some kind of modal state where the exporter waits for the user to use the Node Editor and create their desired input and output sockets. That's a lot of complexity to add.
