Subject: [PATCH] Added playback params to wrapper so speed can be changed
 while paused

You can't modify playback params on the ExoPlayer while paused (see
https://github.com/google/ExoPlayer/issues/4064) so added a member
object which *can* be modified while playback is paused. These
parameters are always applied on start of playback.

Fixes #3651
