remove style whitelist filter

[boygirl]

This PR removes the problematic sanitizeStyles and replaces it with nothing. Instead we will be deprecating Victory's ability to automatically pick up style attributes from the data object. This will be a breaking change, but the upgrade path is pretty simple.

If your data object looks like

data={[
  { x: 1, y: 1, fill: "red", opacity: 0.2 }, 
  ...
]}

Add the following functional styles:

style={{ data:  { fill: (d) => d.fill, opacity: (d) => d.opacity } }}

and everything will work as before
