Updated to YouTube Helper API v0.7.0.
Fixed a bug where the stale video buffer would be continuously rerender after the unscramble effect has been manually toggled off and back on.
Fixed a bug where the video playback state is tied to the audio processing state.
Fixed a bug where the UI button would occasionally disappear.
Fixed a potential memory leak issue where old video/audio context would not be cleaned up.
Move the shader cache more explicitly only used if the current processed video has no changed.
Updated the script to use the more modern requestVideoFrameCallback instead of requestAnimationFrame for efficiency reasons. Fallbacks to requestAnimationFrame for compatibility situations.
Lower to gain of the unprocessed audio stream from the normal 1.0 to a much quieter 0.2.
