This fork needs to disappear

[cezarsa]

This fork only exists because the official version of pexif on pypi is too old and doesn't include some necessary fixes (thumbor/thumbor#287) that are already on source control but haven't been released.

There are issues upstream to track how this is solved:

• As pexif is now on pypi revert from thumbor fork thumbor#294
• Release current master as a new version bennoleslie/pexif#4
