[Feature] Possible to export groups data in different formats

[conde2]

Would be amazing if this add-on could export/import the data in different formats, like XML, JSON etc

My use case is that I have a dedicated server for my Godot game that needs to share data between the client.

Another use case is for creating a versioning control over the data, which would be very useful.

I'm not sure if this can be done in a way that is universally useful, as every project probably would have different requirements on how the data be formatted. Maybe this is better done in a separate EditorPlugin that runs on build and extracts the data from the ResourceGroup resource while formatting it whatever format is required. Another option would be that your dedicated server builds a JSON on the fly from the ResourceGroup's data when the client requests it.
