Replaces the volume slider with a version that offers more control at lower volumes
这些是此脚本的所有版本。 只显示代码变更过的版本。
use better bezier function that actually makes sense
move video selector into harbVolume() and add a check so it definitely works when the slider is used
simplified code and added checks so it loads more reliably
add @downloadURL so the script can be updated via tampermonkey
