This version matches the first major revision of our paper:
- Notable changes to eccentricity definition and branch hierarchy
simplification. Eccentricity is now directly defined by distance to
cluster centroids.
- Fixes to branch-membership centrality measure and the update labelling
function. It no longer changes labels of non-noise points.
- New and updated figures included in the paper.
- Re-evaluated all benchmark notebooks.
- Removed Cython as install dependency.
