Description

This is a new transformer for dih.
I'm often asked to import a lot of fields, many of these fields are read only and sould not be searched.
I found useful to gather them in a single json field, and returning them untouched to the client.

This patch provides a transformer that collects a list of db columns an writes out a json map that contains all of them.

A regression test is included.

A new dependency for jsonic has been added to dih, (already used by langid), I can use a different library if needed.
