* Optimized adler32 implementations. - Adapted adler32 implementation from Crypto++ public domain library. - Added unit tests for adler32 hashing algorithm. * tabified adler32 implementation to match stdlib. * Formatting to be consistent. Make unrolling use macro. --------- Co-authored-by: soerlemans <sebasoerlemans+git@gmail.com> Co-authored-by: Christoffer Lerno <christoffer@aegik.com>
