Wrapper to convert a folium map to .png and save itself.
Warning: to install it, you need selenium (pip install selenium),
and a browser specific executable. For firefox it is geckodriver.
1) download the latest version
2) make it executable: chmod +x geckodriver
3) move it where it needs to be : sudo mv geckodriver /usr/local/bin/
(adding the path to geckdriver to $PATH supposedly works too, but
only the above worked for me).
