NTP helper

[yarikoptic]

E.g. for the helper to present qrcode and send a "start/split" video events, it could also quickly check with our ntp server on the same host, on how far away its clock is

• check if helper could be ran on the scanner console to at least establish tracking of the offset of its clock, if not to adjust it

here are sample quick ntp clients in python https://stackoverflow.com/questions/12664295/ntp-client-in-python/12664736
