This reduces the number of physics checks performed by each
AudioStreamPlayer2D/3D node in the scene.
This is accomplished by setting the default area mask to 0
and exiting early when the area mask is to 0 to improve performance.
Note that in existing projects, the value will only be set to 0
if it was previously set to the default value (1).
The feature can be re-enabled by setting the area mask to 1
(or any other value) on each AudioStreamPlayer2D/3D node.
