Some Olympus Cameras seem to store their makernotes only in subIFDs.
I wouldn't mind juggling bytes but I have no idea where to start :(
start here :
this has a special meaning ::
0x3000: 'RawInfo',
0x4000: 'MainInfo',
they can be either pointers to SubIFDs or arrays
some cameras store the "root tags" in 0x4000 ...
