GenericHash.HashSaltPersonal issue

[DBenS]

Although the code allows using GenericHash.HashSaltPersonal with a NULL key, the "HashSaltPersonal" procedure checks the key against "MIN_SIZE", which causes a function to refuse to work and causes .NET 4.8 compatibility issue.

if (key == null)
      key = Array.Empty<byte>();

if (key.Length > KEY_BYTES_MAX || key.Length < KEY_BYTES_MIN)
                throw new KeyOutOfRangeException(nameof(key), key?.Length ?? 0, $"key must be between {KEY_BYTES_MIN} and {KEY_BYTES_MAX} bytes in length.");
