Multiple audio source synchronisation

[JuliaJakubcova]

I need to play multiple audio tracks simultaneously and in sync. I found older issues with similar requests:
#2855
#4261
and many stack overflow questions about this (like this one https://stackoverflow.com/questions/41128276/android-exoplayer-2-play-multiple-sounds-audio-simultaneously-mergingmedia), so I'm sure many people would be really happy for this functionality.

I think #4261 has the most thorough analysis of the problems and potential solutions to this question. Unfortunately, there isn't an easy way to do this at the moment, but I'll keep this open to track it as an enhancement.

@andrewlewis Assigning to you, as you might be the one working on this in the future. Feel free to duplicate to another issue if there is already a better tracking enhancement for this.
