Previously we would never add annotations if the detection is off,
because we only added an empty list instead of the actual annotations
and would thus break out of writing early. JJ: Enter a description for
the selected changes.
BREAKING CHANGE: Change the `--force/--no-force` cli option to
`--duplicates/--no-duplicates` since it describes a little clearer what
using it actually achieves (adding quote duplicates or not to output).
This allows headers to be created by a formatter, which will
*only* be added to the very first entry created and not to
each entry. Currently for example this is used to create
a csv header but not for each document in turn.
