Basic rewrites don't work with the new PyZX version

[boldar99]

Basic rewrites that need to be fixed:

• [x] Color change
• [x] Fusion of multiple vertices
• [x] Fusion sometimes with a mulit-edge
• [ ] Push Pauli
• [x] Matching ID crashes ZXLive if one of the edges is a multi-edge
• [ ] Bialgebra
• [ ] Copy 0/pi spider

These are mostly issues in PyZX so maybe you should create an issue there as well?
