Feature request: level of detail setting

[fgaz]

Sometimes I'd like to see smaller paths even on lower zoom levels, for example when planning a hike. It'd be nice if there was a setting that allowed me to set the level of detail independently from the zoom level. OsmAnd for example has a "More details" toggle.

Maybe after we finish transition to outdoor-v2, it could be better. #444

Currently we are bound by the data supplied by the vector tiles from Maptiler. It is not possible to fit all paths to eg. continent level zoom, but there is a space to adjust the min level, where they are included. And perhaps not all map style do need to render at that zoom. OpenFreeMap could be probably adjusted more easily.
