preferences window cannot switch between drivers

[gewang]

this affects windows and linux more than mac, the the former have multiple drivers (ASIO, DS, Pulse, ALSA, Jack etc.)\ @nshaheed

refactor miniAudicle.cpp probe()

• get all available audio drivers (rtaudio_compiled_apis)

• validate each driver by trying to instantiate an RtAudio instance with the driver (see probe() line 1204-1209 ish)

• for each valid driver, it needs to get a list of interfaces

• using the default driver and populate the preferences UI

• driver setting load sequence

  0. remember the most recently used driver and selected interfaces
  1. load metadata from persistent settings
  2. if no persistent settings, use default
  3. else validate the driver
  4. if valid load this driver and associated interfaces (load remembered input/output devices; if remembered interface is unavailable use system default for the driver)
  5. else load default driver and associated/default interfaces
