* reading caption and title from several tags with several tests added
minor bugfix for date conversion to MS
optimization: break sidecar loop, when first sidecar is found
* Removed the SideCar Type to make reading sidecar data just as generic as reading the embedded exif data
* Moved metadata-mapping into separate function to prepare for reuse
* Most sidecar metadata is now read with the same function as embedded metadata (for photos). Fixed a bug with rating: 0 being ignored
* added new test for special chars and timezone
* merge incoming changes
* xmp rating fix - 0 is a value. prep for xmp timestamp handling
* refactored mapping of metadata into smaller functions
* consolidated GPS coordinate mapping
* simplification of sidecar date reading logic
* Moved date mapping code into one function - fixed testdata - did not yet resolve offset bug
* CreationDateOffset is now mapped from Sidecar timestamps. Tests updated accordingly.
Total: changed sidecar reading for video to shared reader and fixed tests accordingly (more data is read now)
* 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
Adds parsing of container header data, which provides correct dates
for Matroska files and also fixes the issue that the bitrate shown
in the UI reflects only the video bitrate (not video + audio bitrate).
* Removing ids from DTO as it is not needed on the client side. ~4% saving
* Removing orientation information from DB and server response. ~3% saving
* removing altitude from GPS data and reducing GPS, exposure and fstop precision ~3%
Altogether 10% saving expected.
