Decomposing circular sequences

[veghp]

1. Cut similar-length fragments: the two end fragments in a circular sequence are actually joined and thus the fragment doesn't have the desired length.
2. Cut in featured zones: the issue doesn't apply here. However, this option can be used as a workaround for the above, by specifying !cut regions at regular intervals on the circle.

A simple solution is to add an option to cut_sequence() that adjusts the cut points for circular sequences:

GoldenHinges/goldenhinges/OverhangsSelector.py

Line 382 in b4af31d

if equal_segments is not None:

A full solution could consider any rotation of the sequence. However, this does not seem to be practically necessary.

Suggestions are welcome.
