Integrate Godot executable for server-side user content validation and mutation

[SaracenOne]

Implement a standalone binary version of Godot with a set of scripts for loading and validating scene uploads. Such a pipeline will also allow for features such having the server automatically update legacy content.

Worked on creating a libgodot for such use.

Need to sketch out the basic features needed for this.

Can’t we just have a Godot server set up for this and send data over from the elixir server via some socket?

might reduce the amount of stuff we’d need to maintain
