event handlers are not typed

https://github.com/plotly/angular-plotly.js/blob/5201d97fc2e01e5533d08a921cd44e28265a9222/projects/plotly/src/lib/plotly.component.ts#L80

I was attempting to implement some drill down functionality in the charts in my dashboard. Unfortunately, when I bound a method in my component to the (plotlyClick) output, I noticed that the type of $event was void. But my component method typed the event as unknown anyway, and I console.log the event object, and there is a ton of information in there.

On this line: https://github.com/plotly/angular-plotly.js/blob/master/projects/plotly/src/lib/plotly.component.ts#L241

...I can see that the output indeed is emitting data, just like my logging indicated. Is there anyway we could get these outputs typed? I imagine that the type would be pretty broad due to the amount of different charts/maps out there. But TypeScript thinking that the output is void is probably worse then just not knowing what the event data looks like, but still acknowledging its existence.

Start in projects/plotly/src/lib/plotly.component.ts at the output declaration around line 80 and the emission around line 241. Trace the event payloads emitted by the plotlyClick output and give the outputs a usable TypeScript type broad enough for the chart data; done means consumers no longer see the event as void while the emitted data remains represented.
