Is it possible to extract coordinates of contours generated by go.Histogram2dContours?

HI @jlw welcome to the forums.

I did not find a way to do so. Reading this statement from the [help- sites](https://plotly.com/python/histograms/) is somehow points into the same direction. But maybe I am mistaken.
