Changing color depth from 8-bit (ish) to 6-bit.

This improves PWM duty cycle (brighter!) and reduces that very edge of
flicker it had been exhibiting with clear lensed LEDs like the surface
mount kit uses.

Now with feedback from the initial user builds
Bit crushing in the SoftPWM is better than in the HSV conversion.

Same effect on both timing and brightness, but it's less prone to
visible blockness.
