how to best disable wifi

[jadster]

I read that using Wifi is not great due to interference with the LoRaWAN signal.

I'd like to encourage you to add in the Documentation (readme) a suggested best-practice method to disable wifi for the ttn-zh project. I've found various approaches. But this one seems like a good one to me:

add new line
dtoverlay=pi3-disable-wif
to
boot/config.txt
