[enhancement] Replace DeckScene with AnimationManager

[chrisgervang]

This is a large internal refactor of animation wirings.

Added

• AnimationManager, introduce a draw function to render each frame.
• useDeckAdapter hook, for easy react integration.
• Mutable keyframes using adapter.animationManager.setKeyframes
• Support for any number of simultaneous animations using.
• adapter.seek now draws when called.

Refactor

• worldview's kepler support is less redux-dependent, and is now handled by KeplerAnimation.

Removed

• DeckScene removed, use AnimationManager instead (its library agnostic).
• getCameraKeyframes and getLayerKeyframes removed throughout, now handled by DeckAnimation.
  • removed from adapter.render, adapter.seek, deck scene functions, BasicControls, QuickAnimation

Todo

• api docs
• example docs
