Net hangs if you ask it for a 2xn or nx2 wrapping puzzle with a
unique solution. This, it turns out, is because there is literally
no such thing. Protective constraint added to validate_params(),
with a proof in a comment alongside.

If you really want a 2xn or nx2 wrapping puzzle, you can still have
one if you turn uniqueness off.
