Add man_made=chimney to a future version of the schema #129
Description
Currently at https://taginfo.openstreetmap.org/keys/man_made#values there are 162k of these worldwide, so it's a frequently used value. Usage is spread evenly across the world https://taginfo.openstreetmap.org/tags/man_made=chimney#map ; it's not a value that is used more commonly by some OSM communities to express that concept than others. It's documented at https://wiki.openstreetmap.org/wiki/Tag%3Aman_made%3Dchimney .
It would add value to a general purpose map style that may want to use the Shortbread schema.
It would make sense to add it to:
https://shortbread-tiles.org/schema/1.1/#layer-pois
to mirror the way that man_made=tower is handled.
