CustomAudio Uninitialized config parameter leads to immediate/permanent NullReferenceException

[Raincode]

The parameter overwriteVol is used but not properly initialized in the Awake() function causing what is essentially a crash of the game upon loading into a world.

Suggested fix:
Add appropriate initialization line to Awake() function, e.g.:
overwriteVol = Config.Bind<bool>("General", "OverwriteVol", false, "Overwrite audio volume");
