aaronp64 58931c073d Check for NaN in set_volume_db functions 
Added check in AudioStreamPlayer, AudioStreamPlayer2D, and AudioStreamPlayer3D set_volume_db functions to prevent setting volume to NaN, and give an error.  Using NaN for volume and playing the AudioStreamPlayer could prevent all audio from playing, even from other AudioStreamPlayers.
