[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

Start by locating the Plot component and the Partial definition used for its data prop; the issue does not name a repository file or test. Compare the declared waterfall properties with the connector and measure properties described in the Plotly examples and API documentation. Done means valid waterfall data using those properties type-checks without the reported error.
