[PATCH GnuPG 0/2] Allow AES-128 with Kyber, but force AES-256

The following patch set attempts to fix issue 7472 [1] by:

* when decrypting a session key encrypted to a Kyber key, accepting a
  session key of any size, and simply printing a warning if quantum
  resistance was required;

* when encrypting, force the use of AES-256 (overriding key and user
  preferences if needed) if quantum resistance has been requested, or
  if we only encrypt to Kyber keys and the user did not explicitly
  request a different algo with --cipher-algo.
