Aggregations & transforms UI

If we add the UI for Plotly.js transforms in this component, follow this improved design:

not sure yet if it's going to go into here, but thanks for the reminder on that UI!

@jackparmer as far as you're concerned, the Filter, Group and Aggregate panels should be included in this repo/default editor?

I think that makes sense. Other react-plotly.js-editor users are probably going to want these features as well.
