/**
 * Provides human-readable string representations of tag values stored in a KyoceraMakernoteDirectory.
 * 
 * Some information about this makernote taken from here:
 * http://www.ozhiker.com/electronics/pjmt/jpeg_info/kyocera_mn.html
 * 
 * Most manufacturer's MakerNote counts the "offset to data" from the first byte
 * of TIFF header (same as the other IFD), but Kyocera (along with Fujifilm) counts
 * it from the first byte of MakerNote itself.
