distances are different when toggling i_swap in DFCloudMeshDistance

[DamienGilliard]

When toggling the i_swap, the calculated distances are very different + the faces with the error are not the same:
values ranging from 0.5 to 8 mm:

values ranging from 12.5 to 24.7mm:

@DamienGilliard When coloring the mesh, I guess the problem is we are calculating the distance from the vertices of the mesh to the closest point on the pcd so in case there is a big part of the pcd missing we get bigger values..
