commit 1337b50936ed190a98af1ee6601d857b42a3d296
Author: Holger Dengler <dengler@linux.ibm.com>
Date:   Wed Sep 27 21:54:34 2023 +0200

Add xof state handing for generic sha3 absorb.
    
    The digest life-cycle diagram specifies state transitions to `updated`
    (aka XOF_STATE_ABSORB) only from `initialised` and `updated`. Add this
    checking to the generic sha3 absorb implementation.
