STM32U3 uses 2 banks of 4KB pages and each bank is 128 pages so that gives us 1MB of Flash storage. Can you help to add 2 things:

• support for STM32U3 erase in the form of:
  #ifdef STM32U3
#define EE_ERASE EE_ERASE_PAGE_NUMBER
#endif

• Increase the size allowed for Selected emulation page/sector to 128 pages when manually configure as there is a hard limit imposed of 64 pages in MXCube.
