/*
* This header provides PRIuSIZE, a printf formatter macro for size_t which is similar to the macros
* PRIuX defined in inttypes.h. It is necessary because size_t has different width on different
* platforms (e.g., Linux and ESP32). The alternative would be always casting parameters
* to a certain type in printf and logging functions.
