Gets video element, makes audio context mono.
0.2.2 - Added different icons for when extension is toggled
If you think this is useful, you can buy me a coffee here:
When viewing a YouTube video you may have audio on just one channel(mono).
This extension can fake stereo by doubling the mono channel.
When you first click the extension button, mono(fake stereo) is toggled. On second click, your maximum number of channels per device destination is restored to its initial value.
