// Streaming audio player - agent side
// 20180909 hugo@electricimp.com

// ToDo: lots. Like, parsing the WAV header, transcoding in the agent, etc

// Summary:
// - device asks agent to play a URL
// - agent fetches AGENT_CHUNK sized blocks from the URL using range fetches
// - agent chops these up into DEVICE_CHUNK sized pieces and puts them in
//   send_queue. It then refills send_queue every time it gets down to half
