feat: display additional OSM free data on the map

[rmaree]

Investigate if more OSM "free" data could be imported on the map:

amenity=fountain & drinking_water=yes
Potential sources: amenities with fee=no or payment:none=yes ?
• [social_facility=clothing_bank]
• [shop=charity][payment:none=yes]
• [shop][charity=yes][payment:none=yes]
• [shop=second_hand][payment:none=yes]
• [shop][second_hand=yes][payment:none=yes]
• [shop=charity][fee=no]
• [shop][charity=yes][fee=no]
• [shop=second_hand][fee=no]
• [shop][second_hand=yes][fee=no]
• [amenity=toy_library][fee=no]
*amenity=bicycle_repair_station,fee=no

• amenity=toilets,fee=no

amenity toilets
fee no

OSM also has trees (but should be combined with produce and some kind of filters to display only those producing edible fruits?):

Should avoid duplicate with fallingfruits...
