A wifi scanner for the nodemcu that displays results on 128x64 screen.
Change the fonts using TitleFont and DetailFont. Number of pages of results is determined by DetailFont metrics. You can pick a font from here: https://github.com/olikraus/u8g2/wiki/fntgrp
Once started, it will list pages of wifi networks and their supported standards for about 10 seconds a page, before rescanning for networks again.
