/*
* FTP SERVER FOR ESP8266/ESP32
* based on FTP Serveur for Arduino Due and Ethernet shield (W5100) or WIZ820io (W5200)
* based on Jean-Michel Gallego's work
* modified to work with esp8266 SPIFFS by David Paiva (david@nailbuster.com)
* modified to work with esp8266 LitteFS by Daniel Plasa dplasa@gmail.com
* Also done some code reworks and all string contants are now in flash memory
* by using F(), PSTR() ... on the string literals.
