This patch adds optimized implementations of MORUS-640 and MORUS-1280, utilizing the SSE2 and AVX2 x86 extensions. For MORUS-1280 (which operates on 256-bit blocks) we provide both AVX2 and SSE2 implementation. Although SSE2 MORUS-1280 is slower than AVX2 MORUS-1280, it is comparable in speed to the SSE2 MORUS-640.
