- Removed Adafruit MCP23017 library. Instead, code for controlling MCP23017 is built into library and it uses memory buffer to store all registers data from MCP23017. MCP23017 is now working much faster.
- Example for MCP23017 is changed
- Code for cleaning screen is improved (no more weird black/white lines outside visible aread, which can affect picture quality)
- Better waveform for grayscale (better color pallete), no more weird gradient on one color.
- Improved monochrome mode (writing black color was to aggressive, hard to clean)
