custom crash callback

[JesusCarrascoCarrillo]

Hello, I am starting to use the ESP32 module with the Arduino IDE and I have detected that it produces a reset sometimes, on more occasions than the ESP8266. It is probably for security, although the program I use is the same on both platforms.
In order to debug the error, I would need to have a function similar to the one that the ESP8266 has (extern "C" void custom_crash_callback) to be able to analyze the stack dump. If I work through the serial port I can get the screen dump and analyze it with "ESP exception decoder" but if the equipment is already in production it is impossible.
1.- I would like to propose making this function public, which surely exists since to print the dump on the screen some function must be used.
2.- Another proposal is to dump the produced dumps into a flash file, which can be handled with LittleFS, which would simplify things.

Cheers,
