big flash size though eeprom warning

[traxanos]

Hi

when i use flash sizes greater than a 16bit int, the eeprom methods though warning. is not ciritcal because when you use flash instead eeprom this methods shouldn't use.

<command-line>: warning: unsigned conversion from 'int' to 'uint16_t' {aka 'short unsigned int'} changes value from '1044480' to '61440' [-Woverflow]
lib\knx\src\knx\platform.cpp:144:32: note: in expansion of macro 'KNX_FLASH_SIZE'
  144 |         return getEepromBuffer(KNX_FLASH_SIZE);```
