Room modification endpoints

[TacoConKvass]

What is the addition?

API endpoints for modifying Rooms that are going to be used for world generation.

Why?

Additional modding capabilities

Example usage

Rooms.Modify.Event += (Dictionary<string, CompiledScene_ScriptableObject> room_library) => {
    room_library["Rooms Tutorial"].Rooms[0]....
}

Additional notes

1. Most probably should be implemented through hooking RoomLibrary.LoadCompiledRooms
2. Will require a lot of documentation for the keys of the library
