Description
Last year, I wrote an AVX512/GFNI implementation of the "short" core for Groestl. (Ignore the "long" core code in g512.rs, it doesn't work correctly last I checked). Now that these intrinsics are stabilized, I would love to get this up to the standards of the project and contribute it as an optimized backend.

Research direction
Start by reviewing the linked groestl-gfni implementation, especially g512.rs and its short core, then compare it with the RustCrypto hashes project's existing Groestl backend conventions. Done means the corrected short-core AVX512/GFNI backend meets the project's standards and is validated against the repository's Groestl checks.
