Specifies algorithm parameters for the AEAD component of an HPKE suite
which are determined by standard names as per RFC 9180.


These parameters can be composed into a full HKPE suite name using
`https://developer.android.com/reference/android/crypto/hpke/Hpke#getSuiteName(android.crypto.hpke.KemParameterSpec,%20android.crypto.hpke.KdfParameterSpec,%20android.crypto.hpke.AeadParameterSpec)`.
