Updates the PWM implementation for the PiFire PWM PCB grill platform to use the built-in hardware PWM generator on the Raspberry Pi SoC. This resolves nebhead#156. Previous implementation used gpiozero software PWM; this implementation uses rpi_hardware_pwm library. This is a breaking commit, as the hardware PWM function requires: 1) Installing the rpi-hardware-pwm library sudo pip install rpi-hardware-pwm 2) Adding this line to the end of /boot/config.txt, and rebooting: dtoverlay=pwm,pin=13,func=4 Once these two changes are done, this commit will enable hardware PWM.
