==== Nintendo's EXIF MakerNote Tag ====
'''This still need to be figured out:'''
The MakerNote is made with Tiff Exif information (Big Endian)
first 2 bytes are the IFD Count (IFD is a 12 byte tag), Regulary there are 2 IFDs.
'''IFD structure'''

After the IFDs comes a 4 byte Zero ( {0,0,0,0} ).
And then the Data the IFDs point at (if at all)
