To know how many tags are there, with which type and length. Guess are made on values: if it is an array, first values are printed.
Columns are: context (ifd#, makernote=37500 or exif=34665), offset, tag_name, tag_type, tag_length, tag_raw_value (value or pointer), tag_value (value or array/string)
