servo support

[kitdangerfield]

I am using this to make an EggBot out of an rpi pico 2040, but I need servo support, I've seen that the other Grbl doesn't have servo support, how do I add it to this one

See footnote 13 for configuring the spindle PWM for servo.
Another alternative is the PWM servo plugin, requires board support which very few currently have.
