I have created a pull request that fixes our cURL usage to follow redirects,
and have tested that at least it works with OSM_tiled_mapnik.geo irrespective
of whether that geo file has http: or https:.

I have not tested it beyond that, so will rely on folks testing out the pull
request on other maps before I merge it to the main branch.
