Pavol Žáčik 4bad7cc08f hybrid_mlkem: Convert ECDH shared secret to a fixed-size string 
The shared secret is derived as bignum, and draft-ietf-sshm-mlkem-hybrid-kex
mandates that it is converted to a fixed-size byte array. Not doing this
would lead to incompatibilities with other implementations when the derived
shared secret happens to start with zero bytes.
