WIP Interactive globe from Nico's sources

- The globe is a bit small? Ability to control the max-min size potentially
- Is there a reason why `globe.update()` runs every second? Sounds like a lot of resources?
- Have the ability to control the `addEventListener` of the markers to do whatever (in this case, going to a route by clicking on a link with a sapper-noscroll attribute + changing the href attribute on click - the method `goto` from Sapper scrolls back to top / maybe something to fix with the current transition issues?)
- Edited in `./index.js`:
    1. Using the class as `export default WebglGlobe` instead of Window (as Svelte or Sapper doesn't likayt)
- Edited in `Camera.js`:
    1. Commented line 218: `e.preventDefault();` would cause this error: `[Intervention] Unable to preventDefault inside passive event listener due to target being treated as passive. See <URL>`
