Decrease the frequency of FADD/FSUB in favor of FMUL (#77) 
* this better matches CPU capabilities since execution ports are usually split 1:1 between fadd and fmul
* the frequency of FSWAP_R decreased from 8 to 4 (it's ASIC-friendly)
* activate IROL_R instruction

Different round keys for columns 0,1 and 2,3 in AesGenerator4R (#76) 
* this fixes identical sequences of columns 0/2 and 1/3 if their states are the same
* added TestU01 results for AesGenerator1R and AesGenerator4R
* added a note about the reversibility of AesHash1R
