Simple OLED display code with NodeMCU

This combines the earlier "Simple OLED display code" with a NodeMCU so that it's more compact.

The easiest way to set up the OLED with a NodeMCU is to place the NodeMCU onto a
breadboard so that it takes up holes b1-b15 and i1-i15 on the breadboard with the
micro USB port pointing "up" (it should hang over the edge of the breadboard), and
then plug the OLED pins into holes a9-a15, so that the "CS" pin on the OLED matches
up with the "D0" pin on the NodeMCU (at the "bottom", near the squiggly copper wifi
antenna). OLED pin "VCC" should match up with the "3V3" pin on the NodeMCU, and
OLED pin "GND" should match up with the "GND" pin on the NodeMCU.

In the Arduino IDE, make sure go to Tools > Board and select "NodeMCU 1.0",
otherwise it won't work!
