Another fork

[wspr]

I understand that this repo is no longer active. I started building from this code to improve my Python skills, with the results available here:

https://github.com/AUMAG/ausankey/

The extensions in this work allow multiple columns and many configuration options around automatic sorting of nodes, layout/formatting, and labelling.

When I started this work I didn’t realise there were other active forks so I thought it would be a good idea to comment on it here.
