Struct Increment 

pub struct Increment<T>(pub T);

A derangement d(x) = x + increment.

This is the standard padding function for sponge constructions. A derangement has no fixed points (d(x) != x for all x), which holds as long as the stored increment is non-zero.

Increment(BabyBear::ONE)   // d(x) = x + 1  for field elements
Increment(1u64)            // d(x) = x + 1  for raw integers
