Audio-alert test

This simple datafield lets you hear the possible tones that your watch can produce and shows you their "developer-name". Reason for making this is a question from a user about my Datarun premium datafield (see https://forums.garmin.com/outdoor-recreation/outdoor-recreation/f/fenix-5-plus-series/194951/datarun-premium-4c0---anyone-hearing-the-tones)
