[TypeScript] Missing property in `Partial<PlotData>`

Hi, thanks very much for this handy component!

I tried to look at all examples and API docs available but can't figure out how to make use of connector among other properties (e.g. measure) for a Waterfall chart. I wonder whether there is a generic way to pass those parameters or it's just not possible at the moment?

This is the code I have:

<Plot
  data={[
    {
      type: 'waterfall', 
      x: ['Name 1', 'Name 2'], 
      y: [15, 20],
      connector: {line: {color: 'red'}} // Cause error: Object literal may only specify known properties, and 'connector' does not exist in type 'Partial<PlotData>'
    },
  ]}
  layout={{
    width: 300 
    height: 150
  }}
/>

The root of the problem seems that only limited number of properties are implemented on Partial<PlotData> - including for instance (as shown in example) the marker: {color: 'red'} property - which is NOT relevant to a waterfall chart at all.

Actually, due to my limited knowledge with React/TypeScript, I don't even know how to look at the definition of PlotData (it looks not available on this repo?) in order to inspect what properties are actually implemented there - would be helpful if anyone can provide some pointers.

This might be related to this: https://github.com/plotly/react-plotly.js/issues/247

Beginne damit, die Plot-Komponente und die für ihre data-Prop verwendete Definition von Partial zu finden; das Issue nennt keine Repository-Datei und keinen Test. Vergleiche die deklarierten Waterfall-Eigenschaften mit den in den Plotly-Beispielen und der API-Dokumentation beschriebenen Connector- und Measure-Eigenschaften. Erledigt ist die Aufgabe, wenn gültige Waterfall-Daten, die diese Eigenschaften verwenden, ohne den gemeldeten Fehler einen Typecheck bestehen.
