Bug description:
  pysha3, pypy3, python3.X are affected by CVE-2022-37454, a security issue in Keccak
  https://mouha.be/sha-3-buffer-overflow/

  See: https://github.com/python/cpython/issues/98517

  Testing:

  python3.X/pypy3:

  import hashlib; h = hashlib.sha3_224(); h.update(b'\x01'); \
  h.update(b'\x01'*0xffff_ffff); \
  assert h.hexdigest() == '80762e8ce6700f114fec0f621fd97c4b9c00147fa052215294cceeed'

  pysha3:

  import sha3; h = sha3.sha3_224(); h.update(b'\x01'); \
  h.update(b'\x01'*0xffff_ffff); \
  assert h.hexdigest() == '80762e8ce6700f114fec0f621fd97c4b9c00147fa052215294cceeed'

  For pypy3 and pysha3, I have:
  1. Verified the issues exist in the current packages, with the above tests.
  2. Built the packages with the attached patches
  3. Verified that the packages upgrade
  4. Verified the security issues are resolved, with the above tests.
