This PR adds a monitor mode to the repo. When monitor mode is enabled, no messages or acknowledgements are sent. The component truly acts as a passive listener.
In my case I had a TV and a sound system already connected over HDMI CEC. For some reason the volume control wasn't working so I added an ESP to the existing HDMI connection to listen for volume commands and transmit corresponding IR commands to the sound system. Since the sound system already responds to the CEC messages, I only want to listen for volume commands without replying to not confuse the other CEC participants.
