Allow MSMs to be queried and not just raw commitments. 
This allows us to avoid some interstitial arithmetic in the vanishing argument.

Jack Grigg b4ed5295fe Migrate to group traits 
The `Curve` trait is now `CurveExt: group::prime::PrimeCurve`, and
`CurveAffine` is now `CurveAffine: group::prime::PrimeCurveAffine`.

There is no `CurveAffine` trait in `group`, and it's a widely-used
trait in this crate, so we don't rename it to `CurveAffineExt`.

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.

Jack Grigg f49e1e6177 Fix breakage of trait resolution in Rust 1.49.0 
Previously, `ChallengeScalar` could use the operator traits defined on
the `F: Field` type it wrapped, due to its `impl Deref<Target = F>`.
This was technically ambiguous, and Rust 1.49.0 makes that ambiguity an
error.

We could fix this by adding operator impls with `ChallengeScalar` on the
RHS, but that would conflict with zcash/halo2#111. Instead we manually
dereference every challenge scalar when used in an arithmetic operation.
