/**
* Provides human-readable string representations of tag values stored in a <code>FujifilmMakernoteDirectory</code>.
* <p/>
* Fujifilm's digicam added the MakerNote tag from the Year2000's model (e.g.Finepix1400,
* Finepix4700). It uses IFD format and start from ASCII character 'FUJIFILM', and next 4
* bytes(value 0x000c) points the offset to first IFD entry. Example of actual data
* structure is shown below.
* <p/>
* <pre><code>
* :0000: 46 55 4A 49 46 49 4C 4D-0C 00 00 00 0F 00 00 00 :0000: FUJIFILM........
* :0010: 07 00 04 00 00 00 30 31-33 30 00 10 02 00 08 00 :0010: ......0130......
* </code></pre>
* <p/>
* There are two big differences to the other manufacturers.
* - Fujifilm's Exif data uses Motorola align, but MakerNote ignores it and uses Intel
* align.
* - The other manufacturer's MakerNote counts the "offset to data" from the first byte
* of TIFF header (same as the other IFD), but Fujifilm counts it from the first byte
* of MakerNote itself.
