Port to Godot 4

[Burnsedia]

This project needs to be ported to Godot 4; this could be done by:

• Using the GDExstenstion
• a C++ rapper and GDExtenstion
• a module
  Just to let you know, I have not contributed to this project and have not contributed to Godot Core. I am looking to do so, and If this is a good idea, I am glad to help.

As far as I know Godex requires an engine patch so GDExtension won't work?

There is a pull request for 4.0 compatibility #304
