Add DLNA/AirTunes streaming for iOS app.
IOS app needs to have DLNA/AirTunes option for playback streaming over a wireless network. Lots of consumer audio hardware can stream audio using these protocols. Implementation needs to happen within the app in IOS as there isn’t a global audio settings option that would allow “system” level streaming through a wireless device.
iOS 11 does have global audio settings for AirPlay which works with the iOS app.
