Jack Grigg 5cb838f1a2 circuit: Remove `Copy` impl from `poseidon::pow5::StateWord` 
We will be making it a newtype around `halo2::circuit::AssignedCell`,
which does not impl `Copy`.

Ensure lo and hi incomplete ranges line up 
The previous code assumed that `pallas::Scalar::NUM_BITS` was odd, which is true, but might not remain so after a future generalisation refactor.

Jack Grigg e2c300368b circuit: Pin the proof size 
This is to ensure that if any future circuit changes are made, their
effect on the proof size (if any) will be noticed.

We have now refactored away from the impl From<EccConfig> pattern
so that each sub-config can equality-enable the columns they need.

Jack Grigg 0ede6b2301 mul::Config: Reorder gate definitions 
We are about to extract the sub-configs from mul::Config and refactor
them. Doing so would have moved their gate definitions past the one gate
that isn't created in a sub-config. Reordering the definitions here will
make the subsequent refactor diffs simpler to review.

Jack Grigg a62f9451d1 sha256: Fix `AssignedCell` `From` impls for `AssignedBits` and `Bits` 
zcash/halo2#337 had been updated to account for `AssignedCell`, before
the change to simplify its bounds was made. `AssignedCell` now requires
the `From` impls to take `&VR`.

Jack Grigg 8bd9097e55 Remove `impl Default for Rotation` 
Clippy complained that it could be derived, but what we actually want is
for developers to be explicit about what rotations they are using, for
which `Rotation::cur()` is provided.
