[feat]: video export with hubble.gl WIP

[igorDykhta]

TBD WIP

[chrisgervang]

Tested this PR with the world flights demo. It works minimally, I'll describe what works and doesn't work (apologies if these are already known issues).

Works:

• Dark, Light, Muted Light, Muted Night, Satellite base maps.
• Camera animation and video export (though, no deck layers render so its just a basemap)

Dark basemap works. World flight layers visible in the background, but not in the exporter:

Output: kepler.gl.webm

Non-functional:

• The custom "Kepler.GL Flight Map" works in the main map, but 404s in the video exporter.
• Deck layers do not render
• When the basemap isn't loading correctly and the modal is closed, the app crashes (uncaught error trying to reference a _listeners variable)

When using the "Kepler.GL Flight Map" basemap:

Crash when closing the modal when it failed to load a basemap:

Yes, it's in draft/WIP state. This was the original integration which is obviously out of date with the current kepler/deck versions.
