   Phase control allows to stress less the power supply of LED lights.
   By default all phases are starting at the same moment. This means
   the the power supply always takes a power hit at the start of each
   new cycle, even if the average power is low.

   Unfortunately Arduino Core does not allow any customization nor
   extendibility for the ledc/analogWrite functions. We have therefore
   no other choice than duplicating part of Arduino code.
