aead-stream: remove unnecessary KeyInit constraint on from_aead (#739)

rasendubi · web-flow · commit a20063fd19f1 · 2025-11-02T07:44:47.000-07:00
`Encryptor::from_aead` and `Decryptor::from_aead` require AEAD to
implement `KeyInit`, which seems unnecessary and unused. I believe we
can drop that requirement.
