Deploy: Fix DGtal paths for auditwheel (manylinux)

Allow saving reconstructed image from dmap with vtp suffix

In fact, poly data (.vtp) is recommended for easy reading with Paraview.

If saved with `.vtu`, you have to specify to use XMLPolyReader in Paraview.

Fix Dockerfile, copy folder.

COMP: Do not use module ITKImageIO for ITK less than 4.13

Feature: Add voxelize_graph

Wrapped in sgext.voxelize_graph.
It allows to write the graph into a binary image, with values defined
by the maps: vertex_to_label_map and edge_to_label_map.

It also adds functions to create an edge_to_label_map from a vertex_to_label_map
and a functor: size_t(source_label, target_label).

Also adds cli voxelize_graph, in this case, instead of providing a file
with edge_to_label_map, if the string is == "max" it will use
the function create_edge_to_label_map_from_vertex_to_label_using_max.
