from_meshkernel method: use all attributes

[Huite]

E.g. currently Ugrid2d.from_meshkernel only uses the face_node_connectivity, but not the edge_node_connectivity. This results in a mismatch when edge properties are communicated from the meshkernel, so xugrid will have generated a different edge_node_connectivity in the mean while.

See: Deltares/MeshKernelPy#72

Also edge_face_connectivity once it's available: Deltares/MeshKernelPy#82
