v1.6.2 for ESP32 + ENC28J60

#### Releases v1.6.2

1. Initial coding to port [ESPAsyncWebServer](https://github.com/me-no-dev/ESPAsyncWebServer) to ESP32 boards using ENC28J60 Ethernet.
2. Bump up to `v1.6.2` to sync with [AsyncWebServer_ESP32_ENC v1.6.2](https://github.com/khoih-prog/AsyncWebServer_ESP32_ENC).
3. Use `allman astyle`
