RioGamepad — shared definitions for the virtual HID gamepad driver and its
user-mode client (the RIOJoy tray app's HID feeder).

The input report is fixed-size and has no report ID:
    bytes  0..11  : 6 axes (X,Y,Z,Rx,Ry,Rz), each unsigned 16-bit little-endian
    byte   12     : low nibble = hat (0..3; 0x0F = centered/null), high nibble pad
    bytes  13..24 : 96 button bits (button N at byte 13 + (N-1)/8, bit (N-1)%8)
