function farProgmemIsUsed

Description:
The FlashHelper module in the flash_helper.c file can be optimized for devices with Extended Load Program Memory (ELPM) that do not utilize memory beyond 64kB. It is necessary to implement a function that inspects the memory, particularly the first 100 bytes beyond this limit, to determine if they are being used. This function currently exists as a stub in the flash_helper.c file and needs to be fully implemented. While writing tests for this function would be beneficial, it can be addressed in a subsequent issue if necessary.

User Story:
As a developer, I need a function in the FlashHelper module that checks if memory beyond 64kB is being used on ELPM devices, so that I can optimize memory usage and improve performance.
