Add missing option to sequence.list DB method.

If present and truthy, it will cause the output
to contain two extra fields: missing_raw and
missing_final, each consisting of a JSON array
containing missing raw and final shots for the
corresponding sequence.

In the event that the option was passed but
there are no missing shots, the two aforementioned
fields will still be present and consist of
empty arrays.

Note that this makes the query significantly
slower.
