Add animateTransform motion

[jeffdaley]

Adds an animateTransform motion for transitions that modify one or multiple transform properties.

animateTransform(sprite, {
  scale: {
    from: 0.4,
    duration: 200,
  },
  rotate: {
    from: -10,
  },
  translate: {
    y: {
      from: 25,
    },
  },
  duration: 500, // fallback duration
  easing: easeOutExpo,
});
