[WiP] ESPHome component

[nekromant]

Hi, Folks! First, thanks a ton for all the mods and the firmware. This just makes this oven so worth a buy!

I've recently got mine, flashed with the firmware and now working on a custom esphome component that will drive this oven. Basically an ESP_01 is a ideal fir, since you can hook both reset and boot to GPIO0/GPIO2 and even get emergency reset and OTA functionality.

Anyways, I've got a few questions about the firmware and my work:

• Do you think it's better to create a merge request and keep the esphome component in this repo, so that you can just link this repo in esphome yaml config, or it's better to keep these two apart?
• Is the serial protocol going to change much in future?
• Anybody already working on something similar?

I hope to put my current work-in-progress online the next weekend or so. For now there's not much to check out.
