* Microcode layer redesigned to take advantage of Montgomery ladder
architecture. Instead of R and S there are now two working ("cycle") registers
R0 and R1. After every cycle R0+R1 is placed in register S ("sum"), 2*R0|1
(depending on current multiplier bit) is placed in register T. Then the working
variables are updated, final result ends up in R0.
* Due to the change of working registers, modular inversion routines were
updated accordingly.
* Added optional debugging output control
