Feature: add an animationWhitelist array to the animate prop

[cullenjett]

Addresses #1186

This PR allows users to override the default animationWhitelist for components that accept an animate prop.

When a component has an animate prop it will render itself within a <VictoryTransition /> wrapper, which then renders a <VictoryAnimation /> component with a subset of data to "tween". Initially, that subset was determined by pulling data keys that were included in a module-scoped array of strings (["data", "style", "domain", ...]). These changes allow an animate.animationWhitelist prop to override that array and also moves the default array to a static property on the component so users can reference it if necessary.

There's still room for improvement by allowing users to specify sub-properties they want to animate. For example, instead of enabling/disabling all animations for style it would be great to enable/disable animation for style.fill or style.opacity, etc. That gets a little more difficult when dealing with the data animations though.

Perfect! Thank you for also moving the existing whitelists to statics on each class.
