Class PelExif
Class representing Exif data.
Exif data resides as data and consists of a header followed by a number of PelJpegIfd.
The interesting method in this class is getTiff() which will return the PelTiff object which really holds the data which one normally think of when talking about Exif data. This is because Exif data is stored as an extension of the TIFF file format.

- Return the bytes of the content.
