Likely left over from the Sapling audit.

Jack Grigg 7a6223202e zcash_primitives: Remove redundant TODO 
The primitives are no longer generic over a curve; we hard-code Jubjub,
so we know that the smallest u-coordinate that is not on the curve is 1.

Jack Grigg ed6b7eceef group: Hard-code a w-NAF window size of 4 
We were already ignoring the actual bit length of the scalar, and
selecting the window size based on the maximum bit length, which
effectively hard-coded a window size of 4.

Jack Grigg 1e8fd4da68 group: CofactorGroup::mul_by_cofactor -> CofactorGroup::clear_cofactor 
The generic API now only guarantees that the torsion component is
cleared deterministically; group elements may be multiplied by multiples
of the cofactor (not necessarily the actual cofactor), as long as the
choice of multiplier is fixed for a given implementation.
