Hi all, would anyone know if there is a way to plot contour lines on a Makie mesh ?  
Something like [contour3d · Makie](https://docs.makie.org/stable/reference/plots/contour3d/), but more general.  
With the application I have `contour3d` errors on `Found duplicate x/y coordinates` so I guess some hypothesis is done in the background about that.
