/**
* Provides human-readable string representations of tag values stored in a <code>NikonType1MakernoteDirectory</code>.
* <p/>
* Type-1 is for E-Series cameras prior to (not including) E990. For example: E700, E800, E900,
* E900S, E910, E950.
* <p/>
* MakerNote starts from ASCII string "Nikon". Data format is the same as IFD, but it starts from
* offset 0x08. This is the same as Olympus except start string. Example of actual data
* structure is shown below.
* <pre><code>
* :0000: 4E 69 6B 6F 6E 00 01 00-05 00 02 00 02 00 06 00 Nikon...........
* :0010: 00 00 EC 02 00 00 03 00-03 00 01 00 00 00 06 00 ................
