/*! \brief Class for handling tri color LEDs.

Enable PWM, to set the brightness through velocity or CC, must be on PWM pin and there will be no ability to change colors through velocity values.
Default color will be active if velocity 127 is recieved. For any other values colours will cycle through.
Intensity will change the PWM write value for different colors.
