ESP32-ENC28J60

This Ethernet Library is a copy of the official esp32-arduino Ethernet Library with added support for ENC28J60 boards and all other board types removed.

Low level code comes from the eth_enc28j60 component found in the esp-idf examples folder.

For a more thorough implementation see @khoih-prog's WebServer_ESP32_ENC and AsyncWebServer_ESP32_ENC
