Demonstrate integration between TheatreJS and Deck.gl

[chrisgervang]

POC of an AnimatedLayer, which wraps a Deck Layer with animatable properties using TheatreJS. Each uniform and accessor on a layer can be animated independently, and are grouped together for each layer into theatre.js "Sheet Objects"

• Extract props from Deck Layers to create equivalent TheatreJS props
• Props defined in the application and considered "controlled" and will not be modified by theatre.
• Sub-layer props are not extracted

A similar concept could be done for deck.gl Views, Effects, Extensions, and other components.

While not implemented, animations could be swapped by changing the "sheet" prop, a TheatreJS sheet.
This solution doesn't explore animating individual data elements within a layer.
