No Audio
I have looked into the audio issue and have two choices:

1. I can add audio support and force everyone with ffmpeg to recompile with libfdk_aac codec.

2. I can leave audio support out for a much easier setup.

For now, I am going with #2. Audio may work if you uncomment out [this](https://github.com/Brandawg93/homebridge-nest-cam2/blob/master/lib/streamer.js#L452) line of code, but it doesn't work for everyone. If anyone can find a better way, please let me know here or submit a pull request.
