Add album tracks

[qwerty287]

Adds a new feature that allows to upload GPX tracks/files and link them to an album (only regular, no smart/tag albums). This track is displayed together with the photos on the map, means this is only usable if the map is enabled. To display the track, the Leaflet plugin https://github.com/mpetazzoni/leaflet-gpx is used, it is very easy and only needs one file.

Frontend part of https://github.com/LycheeOrg/Lychee/pull/1274, please also see the notes and explanations there.

I am confused why the CI complains about the formatting when it finds no problems if I run it locally...

It was not my intention to close this PR. As with the other PR for Lychee, this PR got closed when the base branch of this PR consistent_json_api was deleted. Same thing to do as for the Lychee part

• Edit PR and change base branch from consistent_json_api to master
• Checkout the rebased branch and push it here.
