LZ4 decoder in assembly for RiscV RV32IC

Demo to test the Longan Nano screen driver. Display class interfaces with low level hardware. Screen class provide a sprite based frame buffer meant to reduce CPU use by not redrawing sprites already on screen. Demo uses boot button to cycle between five demos.
