[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

首先定位 Plot 元件以及其 data prop 使用的 Partial 定義；該 issue 沒有指定儲存庫檔案或測試。將已宣告的 waterfall 屬性與 Plotly 範例和 API 文件中描述的 connector 和 measure 屬性進行比較。當使用這些屬性的有效 waterfall 資料能夠通過型別檢查且不再出現回報的錯誤時，即表示完成。
