Name: Outdoor fan multi-data field: Multi-altitude
Author: FinnishOutdoorFan

A configurable field that shows three data fields. This is multi-altitued build variant that by default shows current altitude and minimum and maximum altitudes. This build is required so that you can use and configure two instances of same data field individually.

Intended for hiking and walking. Might not be usable while running due to small font size. 

Available fields through settings: 
- timer
- pace
- distance
- altitude (from latest usable or good GPS fix)
- altitude min & max
- altitude reference (first usable GPS fix) and change from that reference

Tested on Garmin Instinct 2X with 4-field (B) layout and 5-field layout.
