Add-on to use builtin Raspberry Pi HDMI CEC hardware from HomeAssistant

Starting from HomeAssistant 2021.7.0, the CEC libraries included in HomeAssistant do no longer support CEC interfaces that are not included in the Linux kernel itself. Therefore, it is no longer possible to control the HDMI-CEC bus through the hdmi-cec integration alone.

However, the hdmi-cec integration supports talking to an HDMI-CEC device over a TCP socket. This add-on launches a HDMI-CEC server which supports the Raspberry Pi hardware interface.
