some advances on assembly coding but no actual gain - yet
part of it in assembly and few k cycles improvement out of 11milion :D
Just written share function in assembly
After writing void share(byte x,byte a[],uint8_t n) from share.c in assembly
number of cpu cycles simulated: 110223221
converted byte xorop(byte a[],uint8_t n) from share.c in assembly
number of cpu cycles simulated: 110223173
