Imprecise compas contour function

[ioannaMitropoulou]

The function compas.datastructures.mesh_contours_numpy produces very imprecise results. (Run 2_basic_slicing_example.py where the issue is obvious)
Investigate if this can be improved, or find better strategies

What is more, there is an issue with the last point of every curve. It seems that it considers every curve closed and adds the start point at the end. As a workaround, for now, I just remove the last point from every polyline outputted by the contours function, but I am not sure if that's the best strategy. Investigate.

True, indeed mesh_contours_numpy produces weird results (I think the functionality might be different from what we are looking for?). I shortly discussed this with Tom last week and he said he will have a look at a way to add a better Mesh slicing/contouring function to compas. I'll ask him if there's some progress this week.

In the mean time I'm also trying to have a look if we can use Meshcut (https://pypi.org/project/meshcut/) for slicing a mesh, this is WIP.
