v1.4

Godot versions: 4.2.x, 4.3.x.

Now it supports for multiple loading screens. You can set three types:

• DEFAULT
• PERSIST
• ONE SHOT

New methods in SceneManager autoload:

• set_loading_screen
• set_loading_screen_from_packed
• reset_loading_screen

Also, append_dependency is renamed to append_resource. I think it is better name because only resource are loaded with ResourceLoader in the backaground.
