Plotly 4.2 breaks figure_factory (when scikit-image isn't installed)

scikit-image needs to be added to dependencies

Thanks for bringing this up, it's a regression and we'll fix it!

Our intention was not to have all figure factories depend on scikit-image, just the ternary contours one I believe.

The workaround for 4.2 until the fix is out is just to install the needed dependencies if you are using a figure factory.

Yep that's what I did :)

Fixed in 4.2.1
