Fix 1548

[kamil4]

Fixes LycheeOrg/Lychee#1548

When I added a few more test images I realized how incomplete our support was across multiple adapters so I patched up what I could:

• Added an abstract MapperAbstract class which implements one method: a recursive trim.
• Added support for IPTC CopyrightNotice to the Exiftool mapper.
• Added support for EXIF Artist, Copyright, and ImageDescription to the ImageMagick adapter.
• Added support for EXIF ImageDescription.
• Added two more test files and extended side-by-side testing of different adapters to cover another existing file.

UTF8 handling is still hit-and-miss though. For instance, the ImageMagick adapter tends to just replace "strange" characters with a dot (.). I added an invocation of convertToUTF8 (which we use in other adapters) in the hope of fixing it but it didn't seem to improve anything. For best results, one should use Exiftool (as always, really...).

The added images triggered some more issues with the recent rounding changes from #54 but this should be all good now...

To fix the codecov status you have to add some more tests to increase the coverage :D
Or you change the config for it to not fail anymore.
