Have a configuration to Crossfade songs

[Uri-Rocky]

This configuration would allow the currently playing track to fade away while the next track fades in A set amount of time to Crossfade of up to 15 seconds should be responsible

[Shredder121]

Note that lavaplayer only can have one currently playing track, and that the pluggable filters work on one track, one frame.

Moreover, my async packet provider already starts the next track 200 milliseconds early, in the name of having more time to provide it to jda-nas.

Starting the next track 15 seconds early is bad. (Although the crossfade might start to be noticable halfway?)

Just my 2 cents

1) Lavalink makes this particularly tricky to accomplish 2) It would be bad for performance due to the change in volume 3) 15 seconds is a lot
