This PR is a follow-up to #3143 and changes the drt wait stats output to geopackage.
However, geopackage does not allow not having a CRS set. Would it be ok to skip the creation if the global config crs is not set? I'm not sure if most people actually set it.

Another idea would be to fall back to .shp again in this case. Or to default to WGS84 or sth...

Opinions?

LGTM However I do not use this functionality so I cannot assess it from the useability perspective.

It also looks good to me. Does that mean the .shp & related files. will be replaced by a single .gpkg file? That would be great! And will the commonly used visualisation softwares (e.g., VIA, QGIS, SimWrapper) also recognize the new file type?

Exactly, it is just one .gpkg file.

That would be great!

It is! :D

I do not know about SimWrapper. However, I know that via and QGIS already support it.
