Tried to do it in Python a few months ago, but failed (I'm not exactly
a great Python coder it seems!).
It should just be a question of creating a loop. Something like this

ok, I can do it... which name should I use for the hierarchical module?
i.segment.hierarchical ?
I change my mind...
Do we really need to make a module only to avoid the user to define a cycle?

Below kept only timings and number of created segments (from previously posted
tests as well as a few new ones), just as a reference.
All tests above threshold=0.95 fail to deliver. The extreme instruction
threshold=0.95 derives 70 segments. Above this, I think that everything would
be merged
