check a return value of *Deserialize

[herumi]

I have changed the return value of blsXXXDeserialize() if MCLBN_USE_NEW_DESERIALIZE_API is defined as the followings.

#ifdef MCLBN_USE_NEW_DESERIALIZE_API
// return read byte size if success else 0
#else
// return 0 if success else -1
#endif
BLS_DLL_API mclRetType blsIdDeserialize(blsId *id, const void *buf, mclSize bufSize);
BLS_DLL_API mclRetType blsSecretKeyDeserialize(blsSecretKey *sec, const void *buf, mclSize bufSize);
BLS_DLL_API mclRetType blsPublicKeyDeserialize(blsPublicKey *pub, const void *buf, mclSize bufSize);
BLS_DLL_API mclRetType blsSignatureDeserialize(blsSignature *sig, const void *buf, mclSize bufSize);

this replicates a bit of what is in wrapInput maybe we could use something like this instead

function wrapDeserialize (func) {
  func = wrapInput(func)
  return function () {
    const r = func.apply(null, arguments)
    if (r === 0) {
      throw new Error('Deserialize err')
    }
  }
}

what do you think?

You are right. I fixed it.
