Render to OLED displays over the I2C bus

This module provides implementations for rendering to OLED displays using a consitent interface. A terminal emulator is also included to make local usage easier.

Individual pixels are accessed using a two-dimensional [x][y] array syntax, where a value of 0 means the pixel is off, and 1 means the pixel is on.
