Suggestion: Track fading

[LaganYT]

Hello,

First off, thank you for making this package, it has really helped me. Anyways, I think it would be cool to have a way to enable fading, choose an amount in seconds to fade, here is an example of how it would work:

station.on(PUBLIC_EVENTS.START, () => {
  station.fadeSongs(3s, true)
});

Hey @LaganYT !
I had some research on the topic long ago and it seems to be a really cpu-intensive task to execute. Do you have any libraries in mind that can do that?
