maps: Port map code into interactive template

[DanielJWood]

The most up to date code is currently here on observable.

We need to port the map over to this repo. To dos include:

• [x] Add this file to the project.json.
• [x] Bring in the code to render the globe.
• [x] Bring in the css to render globe.
• [x] Create the map html template for map-slides
• [x] Trigger scene move/change. Using the ID for the scene found in the content doc (here's the greenland example), match the scene to the trigger column in the google sheet to call the correct lat/lon, zoom, label and other info.

the greenland file was already in project.json

@jsfenfen my mistake, it should have been this file: https://docs.google.com/spreadsheets/d/1yZcjs9ATBOEGHzsACug4kgrRBouki83gvKd6kl1NcbI/edit#gid=0
