Replace aacdecoder lib with Exoplayer on android

[tlenclos]

As discussed here #5 (comment)

Exoplayer is a better, recent, updated lib to handle media.
Example implementation https://github.com/xeodou/react-native-player

I tried ExoPlayer and it's working nice and allow much more control on the stream. See my branch https://github.com/tlenclos/react-native-audio-streaming/tree/android-exoplayer.

Unfortunately it does not support shoutcast metadata, somebody tried to implement it here google/ExoPlayer#466 (comment) but it's outdated and we need to apply this patch on the current version of ExoPlayer (and maybe create a PR).

Are you still looking at replacing aacdecoder with ExoPlayer? is the only holdup getting shoutcast metadata support for ExoPlayer?

[tlenclos]

Yes I still think this is the way to go, and the only blocker is shoutcast metadata support.
