therealyingtong 570f90e4ee SHA-256 chip that uses a 2^16 lookup table

Jack Grigg 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.

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`.
