Multiopen prover never needed evals to be specified.
...
The Lagrange interpolation we were doing was pointless. kate_division sheds the constant
term off each time it is invoked because the quotient polynomial isn't affected by it.
This means we were modifying coefficients that end up getting discarded anyway; the
quotient polynomial coefficients are already determined exactly by the leading coefficients
and the fact that a root exists at each of the points.

Once we refactor the permutation argument implementation to be integrated
as Vec<permutation::Proof>, we can change this again to just map from the
Vec<permutation::Argument> inside ConstraintSystem.
