secp256k1_pedersen_commitment_serialize decompresses the point then recompresses it #293
Description
Ok, yeah, the issue is in libsecp256k1-zkp, not here. For some bizarre reason `secp256k1_pedersen_commitment_serialize` decompresses the point then recompresses it, when all it needs to do is a memcmp (I think). So this function is wasting a lot of time for no reason.
