Is it possible to make it working with ESPAsyncWebServer:

I will add use of LittleFS library instead of SPIFFS here.

Thanks.

The only problem is the method hasArg. If we could find a similiar method in ESPAsyncWebserver, it's done!

I have created another version of WebConfig, to work with ESPAsyncWebserver.
