Elevation data from Viewfinder Panoramas can only be downloaded in chunks of 24 tiles. Direct tile downloads based on latitude and longitude are not supported anymore.
We need to pin numpy to the latest supported version (1.26.4) Usually we pin also Shapely, until compatibility with new version is confirmed. Dependencies of requests (certifi, charset-normalizer, idna and urllib3) are managed automatically by pip install

Rasterio simplifies Python dependency management. GDAL executables are still needed for GeoTIFF creation.
A more reliable source of 1'' elevation data for Europe is now available from: https://sonny.4lima.de While the 3'' data from Viewfinderpanoramas is well-tested and robust, the 1'' data for Europe contains numerous gaps and artifacts.
Better fix for: WARNING: Triangle4XP could not achieve the requested quality! It is worth trying several values before reducing min_angle to 0, for better mesh quality Automated workflow, inspired by @Rastuasi
