f1f23dca82 General intuitivity refactor. Imp'd (IfdTagEntry).ValueBytes().
- Added some assertions and constants. Renamed from variable so it'd be easy to
  tell if the byte-arrays, even though they come directly from the EXIF, which
  specific offsets they start at (so no remove for confusion during enumeration
  and building).

- Except for MakerNote. We're just going to have to skip that when
  writing, for now.
