WIP - Global Charging Map on Google Maps

I've added MULTIPLE maps to this page, so by now it's slow.

This was originally a quick and dirty map showing every single charging point from the global openchargemap data on a google map.
At the moment it's just the UK, twice, and Europe right at the bottom.
The source data is in GeoJSON, with the source data stored on the Google Compute Platform storage. That seems to be the magic combo.

Compared to any of the other maps out there, it loads FAST. Faster than anything else I've seen. Though maybe not three of them on one page.

The horrid colors are because we're trying to programatically change the pin colors. Which Google, for some odd reason, doesn't make easy.
