/** ESP8266Socket class.
    This is a ESP8266 implementation of a socket that implements the SocketInterface class.
    This mock ESP8266 hardware uses AT commands, so an ATParser is used to communicate with the hardware over serial.
    In a non-AT command set, ATParser could be replaced by RawSerial or another hardware communication interface.
