Also investigate mDNS's impact on Async Environment

After 6 hours trial and error concluded this

it's just blocking Async Callback

There is a good outcome we now have a NTP Class derived from Joe's @jjssoftware great firmware https://github.com/jjssoftware/iD8266/

Modified to utilize AsyncUDP Library.

Example from https://github.com/fablab-ka/ESP-Matrix/

It was a good experience.
