rf-notebooks: Permissions on proj directory
In trying to work with pyproj library within the rf-notebooks docker container we see error messages like this on the notebook server stdout:
proj_create: Open of /opt/conda/share/proj failed proj_create: init=epsg:/init=IGNF: syntax not supported in non-PROJ4 emulation mode
Which I suspect is due to the way the libraries are installed. Root permissions for subfolders of /opt/conda/share/proj....
$ !ls -la /opt/conda/share/proj/

a good test for this would be to try to render some vector data with folium ... a little difficult to do in a unit test though. but right now we get a segmentation fault within the container on trying to create a folium.GeoJson(geopandas_df) object
FWIW i tried changing permissions on the directory but no joy.
I suspect perhaps we ought to be pip installing versus conda installing these: https://github.com/locationtech/rasterframes/blob/develop/rf-notebook/src/main/docker/Dockerfile#L15
Now i suspect this is causing a segmentation fault when trying soemthing like geopandas df.to_crs(crs) ... need to get to a minimum reproducible example

I'm worried if we go back to pip we'll run into the problem with packages not all getting resolved from conda-forge.
Which directory and what permissions do you want? We can just set it during the docker build.
