consolidate exif parsing libraries - rework of timestamps (#4)

Browse Source 
* exifr is used for most tags now

* New timestamp handling, removed exif-parser, date supported for png

* Removed offset from testhelper. It's optional

* explanations

* Feature/timestamps (#3)

* preparing for further timestamp test

* Added more test and fixed offset calculation bug

* Revered old dimension test, added new timestamp tests, some bug fixes

* Renamed png-test because faces overrule keywords
