v1.6.4 for ESP32 + LwIP W6100

#### Releases v1.6.4

1. Initial coding to port [ESPAsyncWebServer](https://github.com/me-no-dev/ESPAsyncWebServer) to ESP32 boards using `LwIP W6100 Ethernet`.
2. Bump up to `v1.6.4` to sync with [AsyncWebServer_ESP32_W5500 v1.6.4](https://github.com/khoih-prog/AsyncWebServer_ESP32_W5500)
3. Use `allman astyle`
