HDMI-CEC Part 2

I found a fellow online who apparently has the same issue that I'm trying to solve. They tackled it with an ESP32 and make a super handy guide for everything found here.

I'm going to do my best to mirror that, but also just make it an HDMI pass-through dongle. The idea in mind is an HDMI female port on one side, connected through to an HDMI male port on the other side. I plug that into my computer, then plug a USB-C cable into a USB port on my computer, and I should have HDMI CEC. I've got a buddy that's willing to help my model out a printable case for it. To over simplify things, I'll just be making an HDMI extension, that taps pin 13 for the CEC signals, runs those through an ESP32, translate that into keyboard functions.
