Diesel Version 5:Audio Assist™

Audio Assist™ is a TCS only feature for quick and easy programming from the mainline of any DCC track. While in Audio Assist™ mode the decoder talks to you and walks you through how to program the main features of the decoder. To enter Audio Assist mode press button 8 four times in rapid succession. While entering Audio Assist mode you may hear the decoder say "sound mode active" or "light mode active" that is part of the "Dual Enabled Functions" feature and can be disregarded for now

@TODO make this the audio assist menu tree instead
