Expose Plotly.restyle

[bradpe]

Exposing restyle allows for updating styles on the chart without having to update all of the data.

ie. change the color or size of a marker when clicked.

We are planning on introducing a lower level Plotly.react call which will power this component. It will be smart about applying updates. That way users will not have to think in terms of efficiently applying the plotly.js API and think only about sending in new data.

It will be arriving sometime in 2018 Q1.

Good news! The Plotly.react method is implemented in plotly.js version 1.34.0 and this React wrapper already takes advantage of it, so just upgrade plotly.js and things should be more reactive!

This should address most or all cases where restyle or relayout would have been useful, although I'd love to know if this doesn't meet your needs.
