Fix ESP32S2 compile

[203Null]

For some reason, I can't compile for ESP32 S2 but I managed to get it fixed by changing this.

Original error

Traceback (most recent call last):
File "C:\esp-idf\components\partition_table\check_sizes.py", line 148, in
main()
File "C:\esp-idf\components\partition_table\check_sizes.py", line 142, in main

ValueError: invalid literal for int() with base 0: 'CONFIG_BOOTLOADER_OFFSET_IN_FLASH'

could you provide the git hash of your esp-idf, make sure it is the same as one pointed by submodule under lib/ https://github.com/adafruit/tinyuf2/tree/master/lib

I was using the latest development branch because I was attempting port tinyuf2 to ESP32S3. I tried to recompile with e9cf9e2978 but it won't even compile now.
I'm currently getting a lot of errors like those

/tinyuf2/lib/esp-idf/components/newlib/newlib_init.c:85:6: error: 'struct syscall_stub_table' has no member named '_retarget_lock_init';

I see, the IDF latest move lots of stuffs around and introduce more breaking changes. I am in the middle of other works, will check this out later when possible.
