clang-format -i src/easyaccess.cpp

Hello Kevin,
I was already wondering what I should do after I received a report "Clang Format Checker: All jobs have failed" from GitHub. So thanks a lot for this hint. In case I can contribute some more changes, I will consider this.
GitHub webpage suggested to merge the pull request, which I did now here. Is there now anything left for me? As you may have noticed, this is my first contribution. So any hint to do it right (and especially in a way not to cause unneeded work from others) is welcome.
Kind regards
Norbert

@norbertwg: no problem! I think now you just need to add a test file to Exiv2#2362 and it'll be ready to merge. I think you can use this PR as an example of what to do: Exiv2#2337. In other words, add a new file to test/data and a corresponding .out file in test/data/test_reference_files.
