-Protocol notes:
-- Unless otherwise specified, all structure values are packed in camera native (little
-  endian) byte order
-- Frame buffer and palette data are in native camera formats
-  Some documentation may be found at http://chdk.wikia.com/wiki/Frame_buffers 
-- The frame buffer descriptions returned may not be correct depending on the
-  camera model and various camera settings (shooting mode, digital zoom, aspect ratio)
-  This may result in partial images, garbage in the "valid" area or incorrect position
-- In some cases, the requested data may not be available. If this happens, the framebuffer
-  or palette data offset will be zero. 
-- The frame buffer descriptions are returned regardless of whether the data is available
