==== Nintendo's EXIF MakerNote Tag ====
'''This still need to be figured out:'''
We will address the MakerNote byte array as 'mnote' (i.e. mnote[0] is the first byte)
There is a dynamic byte array at first which its size is at mnote[9].
After the dynamic array starting at mnote[6 + mnote[9]] an 88 bytes array starts.

What is known that on mnote[mnote[9]+72] & mnote[mnote[9]+73] lays the parallax value.
The parallax value is the distance that the right image needed to move in order to get focus.
My formula to get that value isn't so good but here it is:
b0 = mnote[mnote[9]+72]
b1 = mnote[mnote[9]+73]
x = (b1 - 0xC0) << 8 + b0;
Parallax = - round( 2 ^ (x/128 + 2) )
If someone makes sense of this, please explain or maybe correct..
