[patch] Complain about building=roof + addr:*

[Famlam]

Currently there are about 50k cases where addr:* tags are placed on a building with building=roof (not to be confused with building:part=roof)

Addresses are typically not located on (in?) the roof of the building, but rather point at the object that's under the roof. Additionally, as the majority of these tags seem to be for amenity=fuel (60k in combination with building=roof), the wiki page of amenity=fuel also indicates one should make a separate area for the roof.

​https://wiki.openstreetmap.org/wiki/Tag:building%3Droof

Hence, I would propose to add either:

way[building=roof][amenity=fuel] {
  throwWarning: tr("{0} together with {1}, usually {1} is located underneath the roof", "{0.tag}", "{1.tag}");
  group: tr("suspicious tag combination");
}

or

way[building=roof][/^addr:/] {
  throwWarning: tr("{0} together with {1}, usually addresses refer to objects underneath the roof", "{0.tag}", "{1.key}");
  group: tr("suspicious tag combination");
}
