FR: Add .gpx display on the map view

[HEmile]

Since Obsidian supports arbitrary files, one could also link .gpx files (ie trails) in notes. It would be cool to display those files in your vault on the map view. This could be done using this plugin: https://github.com/mpetazzoni/leaflet-gpx .

[esm7]

That's possibly the coolest suggestion as of yet! It also fits very well into the direction this PR started, of reading locations from image files.

Thanks, and indeed! Very interested in how that PR is going to play out as well :)
