Make changes to be able to select the wanted fields that we want to output. We can filter so only those that are requrested will be printed (and will avoid us using cut)
The wanted field are selected in the CSV output form the lib now
Same for JSON, can selected the wanted fields to output
Bump version to 1.3

Make the tool able to use the latest lib feature: selecting one field only

This is the release candidate, the only blocker now is a bunch of valgrind and code review.
