We can go much faster with AVX AES like _mm256_aesenc_epi128 or _mm512_aesenc_epi128. Will work on this

The idea was to optimize using plain c and not spent much time on this but well this is a low prio issue because its not a core feature and for what people use aes in r2 speed is not a problem.
Intrinsics are tied to compilers and wont work on msvc, old gcc or tcc and i prefer readable and maintainable code than fill it with ifdefs
