The feature implemented from issue #257 has a bug, because it treats any two consecutive domains on a strand as though they have a crossover between them, even if they actually have a loopout between them. Re-write the algorithm for finding crossovers (https://scadnano-python-package.readthedocs.io/en/latest/#scadnano.Helix.crossovers) to ignore loopouts.
