`UserEepromBCU2` start-address and size do not comply with the KNX Spec.

[Darthyson]

KNX Spec. 3.0 chapter 06 Profiles 4.2.10 User EEPROM specifies range 0x119-0x46f (855 bytes) for BCU2 User EEPROM.

Current range 0x100-0x3ff

software-arm-lib/sblib/inc/sblib/eib/userEepromBCU2.h

Line 18 in 4e6a918

UserEepromBCU2() : UserEepromBCU1(0x100, 1024, 1024) {};

should be corrected to

// Range 0x000-0x118 (281 bytes) is reserved for loadstates, etc.
// Range 0x119-0x46f (855 bytes) BCU2 User eeprom (KNX Spec. 3.0 06 Profiles 4.2.10 User EEPROM p. 41)
// Flashsize 0x500 for page alignment
UserEepromBCU2() : UserEepromBCU1(0x0, 0x46f, 0x500) {};

Little correction:
The total BCU2 EEPROM range is 0x100-0x4ff (System EEPROM, single chip protected EEPROM, User EEPROM combined).
UserEepromBCU2 is implemented with this total BCU2 EEPROM range, which is fine, but exposes BCU2 system EEPROM to the user, which is not great.
