[Feature] sunburst toggle hidden ring overlay onClick / onSelect

### What problem does this feature solve?

I would like to be able to see a hidden ring with the same shape after an onClick event. The ring would be in the `levels` data with `show` and `opacity` to control visibility. the original ring would then be hidden and moved down in Z dimension. The exposed ring has its own clickable/visible children.

with an onClick or onSelect event I can call `setOption` on the chart instance load new `levels` data to toggle the rings
however this results in the `nodeClick: rootToNode` not rendering.
perhaps `setOption` is not the way to do this?

on the return journey (click in the center) the ring toggling would need to be reversed

### What does the proposed API look like?

The ring toggle is a bit of hack .. there could be `sub-levels` option in the `levels` properties/arguments
