Possible to add support for Folium?

[kburchfiel]

First, thank you so much for putting this project together; it is a huge, huge help!

I'm wondering if it would be possible to add support for Folium (a library that lets you create Leaflet maps within Python). Folium does allow custom tiles to be used within maps, but it expects them to be in https://{s}.yourtiles.com/{z}/{x}/{y}.png format, which I don't think is compatible with OpenFreeMap.

If you're already aware of a way to use OpenFreeMap tiles with Folium, though, please let me know!
