How To Use

Generate a hash of a string.

	string testString = "Test String To Hash";
	Crc32 crc32 = new();
	crc32.Compute(testString);
	uint result = crc32.Value;

Generate a hash of a span.

	ReadOnlySpan<int> testSpan = new int[] { 75849, -246875, 24856, 0, -24867, 9844534 };
	Crc32 crc32 = new();
	crc32.Compute(testSpan);
	uint result = crc32.Value;
