Building an embedded Rust application on top of the ASF4 C vendor library

This is simple yet complete WebServer library for AVR, Teensy, SAM DUE, SAMD, STM32, nRF52, etc. boards running ESP8266 AT-command shields. The functions are similar and compatible to ESP8266/ESP32 WebServer libraries to make life much easier to port sketches from ESP8266/ESP32.
