Write a byte to the EEPROM.
address: the location to write to, starting from 0 (int)
value: the value to write, from 0 to 255 (byte)
An EEPROM write takes 3.3 ms to complete. The EEPROM memory has a specified life of 100,000 write/erase cycles, so you may need to be careful about how often you write to it.
