`poetry add zigzag` failed

[Sajad F. Maghrebi]

Hello

Thanks for the great package.

When I use poetry to add zigzag to my project it fails with this message:

  • Installing zigzag (0.3.2): Failed

  ParseConstraintError

  Could not parse version constraint: >=^0.29

I guess there is something wrong with cython >=0.29 cython dependencey.
