blind_inv_ in oprf.h

[maths644311798]

(1) In yacl/crypto/aead/aead.h,
The annotation “AEAD: Authenticated Encryption And Decryption” is not precise. It should be “AEAD: Authenticated Encryption with Associated Data”.

(2) In oprf/oprf.h,

if (blind_inv_ != 0_mp) {
      MPInt::InvertMod(blind_, ec->GetOrder(), &blind_inv_);
}

looks strange. Should it be if (blind_inv_ == 0_mp)? It seems that blind_inv_ is always 0 in the current program.
