Not zeroizing the state allows to recover any squeezed output. This is because the `ascon` permutations can be inversed. Hence, access to the complete state allows to perform this operation.

Not zeroizing the state allows to recover any squeezed output. This is because the
asconpermutations can be inversed. Hence, access to the complete state allows to perform this operation.This relies on RustCrypto/sponges#57 and a new release of the
asconcrate.
