SbTween/Extensions/AudioExtensions.cs

Extension methods for SoundPointComponent that create and return BaseTween objects to animate volume and pitch over a duration. Each method captures the start value on tween start, updates the sound if still valid using MathX.Lerp, and attaches the sound's GameObject as the tween Target.
