React-map-gl: Use HTTPS on interactive docs

[iamvdo]

There are mixed content errors in Interactive docs, because of HTTP AJAX calls on tiles providers.

Mixed Content: The page at 'https://uber.github.io/react-map-gl/#/' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint 'http://tile.stamen.com/toner/12/656/1582.png'. This request has been blocked; the content must be served over HTTPS.

Yes -- means the examples don't work. Really great docs & examples otherwise!

This is still the case. When you are on https://uber.github.io/react-map-gl/, not http://uber.github.io/react-map-gl/, the tiles from stamen.com do not load. At the moment README.md points to the https version on line 12, which results a lot of confusion to newcomers.

Looks like something is also wrong with the SSL cert for Stamen maps:
https://tile.stamen.com/toner/12/653/1582.png

How about just switching the demo map style to something more reliable?

The url i think can change to //tile.stamen.com/toner/z/x/y.png
