consider adding to scipy

[olgabot]

The lack of optimal leaf ordering in the scipy.cluster.hierarchy module has long been an issue. If you are interested, your code would be highly appreciated :)

There's now a PR from @jamestwebber to integrate this functionality in SciPy: https://github.com/scipy/scipy/pull/7501

The license of this project permits that, but of course it would be quite nice to have an explicit nod of approval from you @adrianveres

Hi @rgommers -- here is my explicit nod of approval! Very glad this code can be useful.

Great, thanks @adrianveres !
