Enhancement - add NetBIOS form lwIP

[AndyW999]

NetBIOS is an easy was to get the IP Address from hostname as most home routers do not to reverse DNS lookup.

I would like to add this as I have this working in STM32 - making the responder work is easy, I have written the code to do the outgoing inquiry too and modified the responder to parse it..

Please could somebody tell me an easy way to import the project into ESP-IDE/

Thanks

Andy.
