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

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.
