pwmleds: less measurements per run
With low-pass filters at the input of PWMLED ADC pins, it is now
relatively stable and noise-free, so we can lower the number of readings

slow ADC inputs
The fastest-repeated measurements are needed for PWM LEDs. OTOH,
things like buttons, battery voltage, ambient lights, etc. can be
read less frequently, and should be read in a deterministic time frame.
So we will measure PWMLED current in the free-running mode (as fast
as possible), and the other "slow" ADC inputs with each PATTERN_DIV-th
timer tick.
