[Library Manager] EthernetWebServer_STM32 library for STM32 boards

[khoih-prog]

https://github.com/khoih-prog/EthernetWebServer_STM32

This library currently supports

1. STM32 boards with built-in Ethernet such as :

• Nucleo-144 (F429ZI, F767ZI)
• Discovery (STM32F746G-DISCOVERY)

2. STM32 boards (with 64+K Flash) running EMC28J60 shields

This is simple yet complete WebServer library for STM32 boards running built-in Ethernet (Nucleo-144, Discovery) or EMC28J60 Ethernet shields. The functions are similar and compatible to ESP8266/ESP32 WebServer libraries to make life much easier to port sketches from ESP8266/ESP32.

The library supports

1. HTTP Server and Client
2. HTTP GET and POST requests, provides argument parsing, handles one client at a time.
