Add support for vector layers

[pierotofy]

It might be useful to allow the visualization of vector layers.

This is a bit tricky, as it would most certainly need the inclusion of a software like https://github.com/mapnik/mapnik to scale and use styles properly.

We would also need to create a geo-CSS parser (or port something like https://docs.geoserver.org/stable/en/user/styling/css/index.html )

Or perhaps just https://gdal.org/drivers/vector/mvt.html + https://openlayers.org/en/latest/apidoc/module-ol_format_MVT-MVT.html

Vector tiles seem promising

Hello @pierotofy I am trying to view contours on DroneDB.

My work around was import the DEM to QGIS, include the contours, export as a map and upload back to the hub.dronedb.app

Maybe using vector tiles is a simpler solution. Is this already working or is there a workaround for it?
