Download gridadmin geopackage if available

[leendertvanwolfswinkel]

When downloading a schematisation revision, it is currently already checked if a valid model for this revision is available and if so, the gridadmin.h5 file is downloaded.

We now have a new endpoint from which the GIS representation of the gridadmin (in GeoPackage format) can be downloaded:

/v3/threedimodels/{id}/geopackage/download/

Please download this file as well (to the same folder as the gridadmin.h5) if it is available. If it is not available, make sure the process continues without errors.

@leendertvanwolfswinkel Looks like a threedi-api-client with a new endpoint support is not released on PyPi yet. I would need it released first to finalize this ticket and prepare PR.

I have notified @jpprins1 of this, I expect a new threedi-api-client to be released soon

[leendertvanwolfswinkel]

@ldebek The real release of threedi-api-client will have to wait until it is released onto production, but a beta release has been made available https://pypi.org/project/threedi-api-client/4.1.2b0/

@leendertvanwolfswinkel Changes available for testing on branch: https://github.com/nens/threedi-api-qgis-client/tree/downloading_gridadmin_geopackage

The requested features all work as they should. However I now realize I want some more and some changes (sorry for the feature creep...):

• [x] Also download the gridadmin.gpkg when downloading results (download to the grid folder as well as to the results folder)

@leendertvanwolfswinkel Change requested above applied.
