in `slash()`, `id_commitment` is calculated wrong?

[bkomuves]

It seems to me, that when computing id_commitment in slash():

logos-lez-rln/methods/guest/src/bin/rln_registration.rs

Line 490 in a890f1c

let id_commitment = hash_pair(&identity_secret, &[0u8; 32]);

to be compatible with Zerokit, you would need to use compress_1() instead of hash_pair() (which in turn uses compress_2()).

let id_commitment = poseidon_hash(&[identity_secret])?;
