add onMouseOver / onMouseOut events

[lucafalasco]

It would be useful to add mouse events handlers to each element of the data visualizations, in order to make it possible to pass a callback to handle those events to eventually trigger side effects.
This could be done similarly to how it currently works with the tooltip prop.
I think something like this could work:

interface Props {
  ...
  onMouseOver?: (e: React.MouseEvent, d: Datum) => void
  onMouseOut?: (e: React.MouseEvent, d: Datum) => void
}

Can you please provide a little more details on it?
