ESP8266 flash lifx lights
/* This is made for a ESP8266 (i use a wemos d1). It uses the udp lan protocol to flash the lights.
* This program will let your lifx lamps flash purple seven times when a switch is pressed.
* When it has a wifi connection, a led will go on.
* I started from code by daniel_hall at https://community.lifx.com/t/sending-lan-packet-using-arduino/1460/3
