+MacroPad HID keyboard and mouse demo. The demo sends "a" when the first key is pressed, a "B" when
+the second key is pressed, "Hello, World!" when the third key is pressed, and decreases the volume
+when the fourth key is pressed. It sends a right mouse click when the rotary encoder switch is
+pressed. Finally, it moves the mouse left and right when the rotary encoder is rotated
+counterclockwise and clockwise respectively.
