commit dddf507557
Author: Tino Reichardt <milky-7zip@mcmilk.de>
Date:   Sun Jun 18 09:13:59 2023 +0200

    Add SHA3 hashing

    - added these variants: SHA3-256, SHA3-384, SHA3-512
    - reordered also the hashing id's
    - added some notes about them in DOC/Hashes.txt

    Signed-off-by: Tino Reichardt <milky-7zip@mcmilk.de>

The cherry-picking was a chaos; they're not applied in order, and some
commits even got cherry-picked twice (1->4->0->2->4->3). So subsequent fixes and
adjustments were applied to make it build.
