Insert a blank track in a CUESHEET block at the given index.
A blank track is one in which all field values are zero.
\param object A pointer to an existing CUESHEET object.
\param track_num The index at which to insert the track. NOTE: this
is not necessarily the same as the track's \a number
field. The tracks at and after \a track_num move right
one position. To append a track to the end, set
\a track_num to \c object->data.cue_sheet.num_tracks .

\code object->data.cue_sheet.num_tracks >= track_num \endcode

\c false if \a copy is \c true and malloc() fails, else \c true.
