This PR adds a new EEPROM erase feature.
An currently open PR to the x16-smc project makes it possible to write to and read from the EEPROM. If this feature is released, we could end up having data in the EEPROM that prevents booting the system. We can get out of such a situation by enabling the bootloader to erase the EEPROM.
The bootloader's default operation is still not to touch the EEPROM.
The new I2C command (0x86) lets you set a flag that determines whether or not the EEPROM is erased. If bit 0 of the flag is cleared (=0), the EEPROM is preserved, and if it is set (=1) the EEPROM is erased. After erasing the EEPROM, all addresses have the value 0xff.
