See if mapview is worth the effort

Seems to allow displaying an interactive map as background, openstreetmap based by default.

Might be cool to be able to import+export from/to GIS software.

Check if

• other tiles engines might be available, eg for HD satellite view, eg test with Luxembourg opendata geographic data EU Inspire
• ease to move other interactive widgets on top (markers?)
• able to add grid on top (automatically or using a JSON layer?)
• able to show level lines
• light enough on hardware resources (important)
• usable offline (caching...)
• export to GIS (kml, geoshapes?)

I put it with target 1.3 for now, but if you feel it's worth looking at earlier just change the milestone :⁠^⁠)
