Optimizations

[shreyas-jadhav]

1. Apply effects in single pass

• fadeIn(0.05).fadeOut(0.05) -> fadeInAndOut(0.05)
• delay(0.1).trim(0,5) -> delayAndClip() | delayClipFadeInAndOut
• trim(0,5).fadeInAndOut(0.05) -> trimAndFadeInAndOut(0,5,0.05)
• delayReverbClip

2. We don't need to re-apply delay and reverb at loop points.

• apply delay and reverb at once on load,
• only apply micro fadeIns and fadeOuts, and trims()
