New library ESP_EEPROM - improved EEPROM emulation library for ESP devices

[jwrw]

The standard EEPROM library for the ESP8266 uses flash memory to store the EEPROM data. This is re-flashed every time the dates committed, which is slow, disruptive and will wear the flash prematurely. This library is substantially compatible with the standard library but avoids re-flashing as much as possible.
