Watchfaces

Check out esp32-lvgl-watchface project to see how watchfaces are converted from binary to LVGL code. You can add more watchfaces but you will be limited by the ESP32 flash size. In that case you can only compile your favorite watchfaces. Links to the pre-built binary watchfaces are included.
