Support New Zealand's LDS map tiles

[Glodenox]

Requires the use of a free API key, made available as Creative Commons Attribution - which we can manage just fine. Just having the API key shared in the script isn't ideal, but I'd rather not start writing special stuff for that.

It is not available as WMS, so this depends on issue #23 (Support XYZ format).

Can the NZ map be loaded / used at this stage or is there more work required.

Hey there! At this point it is not yet possible to add the New Zealand map, as the script currently only supports maps that are provided in a WMS service. Last I looked at this data, it seems to be relatively easy to add once I've applied the changes for XYZ map type support. The main issue has been the support for multiple coordinate systems without breaking the map editor as a whole, but I should have that part resolved. It now just comes down to finding the time to bring it all together.
