[Imports] Initial import of LINZ address data to OSM is complete.

[Eliot Blennerhassett]

Greetings all,

I'm happy to announce that the initial import of 1.9M New Zealand
addresses from LINZ to OSM is complete[1]  (about 40K addresses were
already present)

Thanks to Rob Alley linz_robA (825,470 nodes) for his persistence!
Also thanks to aaron_linz, gaddman_linz, Ironman324 for their contributions.

This doesn't mean we have absolutely 100% coverage or 100% accuracy. For
instance, where the LINZ data had many addresses at a single point,
these were often deleted from the import i.e. left for a later update
when a way of dealing with them is determined.

The existing addressed objects in OSM were not checked in detail for
consistency with the LINZ data.

A different approach will be required for maintenance vs this initial
import.  I'm looking at Norway[2] as a possible model.
