Function full_round 

pub fn full_round<F: Field, SC: SpongeConstants>(
    params: &ArithmeticSpongeParams<F>,
    state: &mut Vec<F>,
    r: usize,
)

Apply a full round of the permutation. A full round is composed of the following steps:

• Apply the S-box to each element of the state.
• Apply the MDS matrix to the state.
• Add the round constants to the state.

The function has side-effect and the parameter state is modified.
