be a bit more lenient when determining if a node is an address node

consider some additional tags as "not interesting"/non-POI-like:
* check_date/fixme/note/note:*/survey:* — mapping related tags
* layer/level/level:ref — can be considered attributes of the address
* ref:* – often used to indicate a source ID on imported data
