If you would like to modify the web interface, you can!
The web/ folder contains all .html, .css, .js files.
You can edit and test them locally as long as you’re connected to the WiFi Duck
network thanks to the websocket connection handled by JavaScript in the background.
To get the new files onto the ESP8266, run python3 webconverter.py in the
repository folder.
It gzips all files inside web/, converts them into a hex array
and saves it in esp_duck/webfiles.h.
Now you just need to flash the ESP8266 again.
