Automatically flashes esp32 and finds airtag data

[luu176]

Run python script while airtag off (remove battery), when it lists available airtags, turn on airtag (put battery in) near esp32. then select the airtag. A new .keys file will appear with title of airtag mac address and advertisement key will be inside

This looks really good! Can you add the arduino sketch that generates the new bin files you've uploaded here? That way I can look over how they are generated/different from my original script.

the file airtag_sniffer_json.ino is now there. It gets the payload and mac address and task and prints it in the serial for easier reading for the python script.
