CI: fix testdata: broken NRW Hausumringe dataset URL

[neteler]

Replace huge 859.7 MB file hu_EPSG4647_Shape.zip (which no longer exists within openNRW) with a 70 MB gru_vereinf_05314000_Bonn_EPSG25832_GeoPackage.zip file from https://www.opengeodata.nrw.de/produkte/geobasis/lk/akt/gru_vereinfacht_gpkg/

Fixes #29 and probably also fixes #5

Requires #28

Merci

@anikaweinmann As not being very familiar with the test, I don't manage to complete this PR. If possible, please continue it.

The tests are running in grass -c epsg:3358 /grassdb/nc_spm_empty. I can try if I find the problem

[neteler]

grass -c epsg:3358

I guess that EPSG:25832 collides with EPSG:3358 (can the former be reprojected into the latter?).
Maybe change it to use --tmp-location, and with the EPSG code of the dataset?

OpenCode Deepseek v4 Flash kindly changed in 78e3dc7:

1. download_urls.py: Added BUILDINGS_LAYERS = {"NW": "GebauedeBauwerk"} - the new NRW dataset is a multi-layer GPKG (cadastral data), and GebauedeBauwerk is the buildings layer (layer index 2, not the default layer 0 Flurstueck)
2. v.alkis.buildings.import.py:

• import_single_alkis_source() now accepts an optional layer parameter
• The three v.import calls use a shared options dict that includes layer when provided
• main() reads the layer name from BUILDINGS_LAYERS.get(fs)` and passes it through

Locally the NW test now works, in the correct EPSG:25832 project/mapset:

.OK

OK

Apparently the globally set AOI now fails (it doesn't make sense anyway in the NC projection.
