Memfault ESP-IDF "As-Lib" Example Project

This project shows how to integrate the Memfault SDK into an ESP-IDF project that's using a custom CMake build setup, as described in this document:

https://docs.espressif.com/projects/esp-idf/en/v5.1.1/esp32/api-guides/build-system.html#using-esp-idf-in-custom-cmake-projects

The example is based on the examples/build_system/cmake/idf_as_lib example:

https://github.com/espressif/esp-idf/tree/v5.1.1/examples/build_system/cmake/idf_as_lib

Building this Example

First setup and activate ESP-IDF environment (this example is only tested with v5.1.1).

Then run the following commands to build the example:

# see the justfile for the commands this runs.
# if you have the just program installed, you don't need to use the ./just.sh
# wrapper.

# build the project
./just.sh build esp32s3

# flash and start the serial monitor
./just.sh run esp32s3

This should drop you into a serial console on the esp32 board:

You can test crashes + exporting data (export command for base64 chunks).
