Panning for Android

[sepans]

I did a simple implementation of panning for Android by modifying setVolume and setPan in sound.js. I don't know if it is the right way for doing it but documenting it here in case it is useful:

Sound.prototype.setVolume = function(value) {
  this._volume = value;
  if (this._loaded) {
    if (IsAndroid) {
      var leftVolume = value < 0 ? this._volume * (1 - Math.abs(value)) : this._volume;
      var rightVolume = value > 0 ? this._volume * (1 - value) : this._volume;
      RNSound.setVolume(this._key, leftVolume, rightVolume);
    } else {
      RNSound.setVolume(this._key, value);
    }
  }
  return this;
};

Sound.prototype.setPan = function(value) {
  if (this._loaded) {
    if (IsAndroid) {
      var leftVolume = value < 0 ? this._volume * (1 - Math.abs(value)) : this._volume;
      var rightVolume = value > 0 ? this._volume * (1 - value) : this._volume;
      this._pan = value; //should this be outside of if(this._loaded)like setVolume?
      RNSound.setVolume(this._key, leftVolume, rightVolume);
    } else {
      RNSound.setPan(this._key, this._pan = value);  
    }
  }
  return this;

Thanks
