Fade in/out for GrainPlayer

[l-irizarry]

The feature you'd like
A way to apply .fadeIn and .fadeOut to a GrainPlayer, like we can for the Player.

Any alternatives you've considered
One alternative I saw is to use player.volume.value, and then use one of the rampTo functions, but I'm not sure how to apply those at the beginning and end of a player to simulate the fade in/fade out between tracks. Is this possible?

Any other alternatives are welcome. Thank you!
