The first idea was to move util timer task to 2nd cpu later, but it turned out taskhandling slows down a lot
Therefore it had to be moved
Move init of timer into main loop
Add a bitfield for usage of pins for soft pwm
Add handling of soft pwm pins to jshPinSetState
Add handling of soft PWM to jshPinAnalogOutput if soft:true is set in options
Set time for util timer to a min of 30 usecs
