- Mode 2: Immediately on next FPGA clock rise
Added ability to enable/disable a single inverter leg outside of global PWM enable for @anirudhupadhyaya .

I think this is ready for review. I might want some tips on how to test these new features, I'm sure I can apply some of the changes to our bench setup.
