[FEATURE] Support refresh rate change

A little more information.

If one uses the android MediaCodec (so not the ffmpeg ones) then you can let android do most of this.
You can set setVideoChangeFrameRateStrategy on the ExoPlayer object to one of the enum values. I'd just set it to CHANGE_FRAME_RATE_ALWAYS.

For the ffmpeg side of things you'd have to first get the framerate from the source and then set that framerate through a different code path on the player Surface object.

I would have tried this in code but my compile is having serious issues and different issues every time (mind boggling.. i hate the android build stack, so full of many mysterious failure points).
