    Description

      On .NET 5 and later we can use ARM intrinsics to perform CRC32 calculations for key hashes. This will improve performance whenever we're running on ARM CPUs.

      Example implementation: https://github.com/brantburnett/Snappier/blob/77dc523e57b04d498953e629292254e02360dd39/Snappier/Internal/Crc32CAlgorithm.cs#L49-L79

      Note the above example is CRC32C, but there are matching intrinsics for CRC32.
