Nonce Reuse in HPKE Context

The sequence number that is used to compute the AEAD nonce when using a re-usable HPKE context is incremented after each seal or open operation. This sequence number was stored as a u32 and used regular addition on u32 for the increment, meaning in release mode it would silently wrap around to 0...
