/*
The primary goal of this function is to add phase control to PWM ledc
functions.
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.
Phase control is also of major importance for H-bridge where
Phase control is also of major importance for H-bridge where
both PWM lines should NEVER be active at the same time.
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.
WARNING: this means it can easily break if ever Arduino internal
implementation changes.
