[BUG] downloads are done on every call instead of just once

[WolfgangFahl]

Describe the bug Openresearch tests show multiple download actions:

Downloading /Users/wf/.geograpy3/countries_geograpy3.json.gz from https://raw.githubusercontent.com/wiki/somnathrakshit/geograpy3/data/countries_geograpy3.json.gz ... this might take a few seconds unzipping /Users/wf/.geograpy3/countries_geograpy3.json from /Users/wf/.geograpy3/countries_geograpy3.json.gz warning: unsupported type <class 'list'> for field labels Downloading /Users/wf/.geograpy3/regions_geograpy3.json.gz from https://raw.githubusercontent.com/wiki/somnathrakshit/geograpy3/data/regions_geograpy3.json.gz ... this might take a few seconds unzipping /Users/wf/.geograpy3/regions_geograpy3.json from /Users/wf/.geograpy3/regions_geograpy3.json.gz warning: unsupported type <class 'list'> for field labels Downloading /Users/wf/.geograpy3/cities_geograpy3.json.gz from https://raw.githubusercontent.com/wiki/somnathrakshit/geograpy3/data/cities_geograpy3.json.gz ... this might take a few seconds unzipping /Users/wf/.geograpy3/cities_geograpy3.json from /Users/wf/.geograpy3/cities_geograpy3.json.gz

To Reproduce Run tests of OpenResearch

Expected behavior Download should only happen once
