Force audio to play in one ear
Put audio from YouTube or Twitch in one ear, to help listen to multiple things simultaneously.
Doesn't work in the Twitch clip editor, for some reason. Probably because it's already using the Web Audio API and I haven't done anything to handle if a page is already using it.
If you want me to toss another site on the list, just ask and I'll see if it works.
**v0.1.1**: Fixed bug where the option to go back to stereo just put the left channel on both sides.
