badge23: nearly fully split

Making progress on #2 (closed) .

Only thing left is captouch, but I'm leaving that until one last refactor by moon2.

components/badge23/include/badge23/espan.h

-#pragma once
-#include <stdint.h>
-void os_app_early_init(void);
-void os_app_main(void);
-uint8_t hardware_is_initialized(void);
