Convert piui menu system to use circuitpython displayio module #1
Description
Currently the menu system "piui" uses the retired adafruit python module for the SSD1306 display.
This menu system should be converted to use the newer Circuitpython displayio modules and the new circuitpython driver for the SSD1306 display. Currently the sensor python modules use circuitpython, so I would like all of the modules use the same hardware libraries (Circuitpython/blinka )
Another benefit of converting to blinka is that it should be easier to support newer/better/cheaper displays like the 1.3" 240x240 IPS color display that adafruit sells.
