Related to !147, I would like to not only go from pantools_DB -> GFA but also vice versa. This merge request collects my tries of doing that. It's marked as draft for now because I'm not sure if I'll use this code in the end.
TODO:
Fix kmer index
Make working on cyclic graphs
Find out what happens with degenerate nodes
Don't require genome locations file if GFA is provided (if GFA contains sequences)
