Plays positional sound in 2D space.

Plays audio that dampens with distance from screen center.
See also $(D AudioStreamPlayer) to play a sound non-positionally.
$(B Note:) Hiding an $(D AudioStreamPlayer2D) node does not disable its audio output. To temporarily disable an $(D AudioStreamPlayer2D)'s audio output, set $(D volumeDb) to a very low value like `-100` (which isn't audible to human hearing).
