Let's introduce the other major player

My plans for the VSCode map extension now extend beyond just OpenLayers

At this point there are some small oddities:

• The timeline button SVG has broken hrefs. You can see it from the missing play/pause/rewind graphics.
• The Cesium InfoBox doesn't work.

This is probably due to a combination of:

• Running cesium from the local file system
• The VSCode/Electron webview or Cesium itself imposing sandboxing restrictions that breaks the InfoBox

Still, for the purposes of being able to quick and easily preview CZML content, this is a very nice starting point.
