Struct Poseidon2ExternalLayerMonty31

pub struct Poseidon2ExternalLayerMonty31<MP: MontyParameters, const WIDTH: usize> { /* private fields */ }

The external layers of the Poseidon2 permutation for Monty31 fields.

This is currently not optimized for the Neon architecture but this is on the TODO list.
