FEATURE FOCUS: Automatically update audio devices when changes are detected (MacOS)

Audition (Beta) now supports automatic switching of default input and output devices when changes are detected to the default Mac OS settings.  By default, Audition now uses "System Default" as the Input and Output Device options in the Audio Hardware preferences.  Now, when plugging in headphones, a USB microphone, or connecting bluetooth listening devices that MacOS uses as the new default, Audition will automatically switch to use these devices for playback and recording as well.

Certain devices, such as Apple Airpods, have limited sample rates for their microphones which can cause playback degradation.  In this situation, Audition will change the default audio output device, but disable the input device, to ensure full fidelity.  Users can override this behavior by selecting the limited input device manually, as before.
