cumulativeElevationLoss is missing in stats

[jesuspicornell]

Problem description

1. v1,0RC5
2. PHP 7
3. cumulative elevation loss is missing in stats.

For example, when I calculate the stats of a GPX file, I get this answer:

[{"description":"Osterrunde um Bergen-Vogtland.gpx","distance":20843.2107222357080900110304355621337890625,"avgSpeed":0.98572762933249979955263597730663605034351348876953125,"avgPace":1014.4790206166434245460550300776958465576171875,"minAltitude":444.1000000000000227373675443232059478759765625,"maxAltitude":601,"cumulativeElevationGain":370.7000000000001591615728102624416351318359375,"startedAt":"2020-04-12T00:41:05+00:00","finishedAt":"2020-04-12T06:33:30+00:00","duration":21145}]'

It is also missing in this document: https://github.com/Sibyx/phpGPX/blob/69846b781000c12c15eea26c2808fe67f0305802/docs/phpGPX-Models-Stats.md

Expected behaviour

[{"description":"Osterrunde um Bergen-Vogtland.gpx","distance":20843.2107222357080900110304355621337890625,"avgSpeed":0.98572762933249979955263597730663605034351348876953125,"avgPace":1014.4790206166434245460550300776958465576171875,"minAltitude":444.1000000000000227373675443232059478759765625,"maxAltitude":601,"cumulativeElevationGain":370.7000000000001591615728102624416351318359375,"cumulativeElevationLoss":370.7000000000001591615728102624416351318359375,"startedAt":"2020-04-12T00:41:05+00:00","finishedAt":"2020-04-12T06:33:30+00:00","duration":21145}]'

Possible solution

A possible solution if you have any.

Something interesting or funny

Joke or interesting fact to made readers better day :) For example: Ants get drunk and act silly, causing their friend-ants to throw them in puddles of water.
