NTP time for ESP8266 and ESP32

NTP time example for ESP8266 and ESP32 based on standard functionality

See video: https://youtu.be/r2UAmBLBBRM

Correction: The time() function only calls the NTP server every hour. So there is no need for the function getTimeReducedTraffic(). The function getNTPtime() does more or less the same... Thank you, Jose Baars for your testing!
