Adds functions to turn on audio monitoring to allow the user to hear playback of an audio source over the user's speaker. It can be set to turn off monitoring and only output to stream, or it can be set to output only to monitoring, or it can be set to both. On windows, audio monitoring uses WASAPI. Windows also is capable of syncing the audio to the video according to when the video frame itself was played. On mac, it uses AudioQueue. On linux, it's not currently implemented and won't do anything (to be implemented).
