Feature request: Fade dark background out as panel is minimized

[spsaucier-bakkt]

It would be great to have the background fade out when the panel is slid down. That seems to be the behavior of all similar interactions using this slide-down paradigm.

Currently, the dark backdrop disappears suddenly when the panel is dismissed. I've had to work around this by trying to use it as a react-navigation screen that animates its own background on dismissal, though that has come with its own issues, and support in this library would be simpler all around.
