We use binary operators specifically to implement constant-time scalar
multiplication.

0a4db20d82 impl group::cofactor::CofactorGroup for Pallas and Vesta
Prime-order groups can be treated as a group with a cofactor of 1,
allowing them to be used in cofactor-aware protocols like RedDSA.

bd17c726ac Add a Selector type
This currently just wraps a `Column<Fixed>`, but enables us to start
writing circuits that can later have their selector usage optimised.

4f17322c2d Allow Chip::load to return state that the Layouter will hold
This enables chips that e.g. want to load multiple lookup tables into
the same columns to store state about where each table was layed out.

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`.

55fb581f17 Define hash-to-curve over Curve, not CurveAffine
This removes an unnecessary layer of indirection from the type system,
and ensures that these APIs depend on the halo2-specific trait with the
extensions we require.
