Adds --start-at-preview and --stop-at-duration and --stop-at-pts options. These correspond to the job->start_at_preview and job->pts_to_stop variables the MacGui and LinGui use to achieve live preview encodes.

While of course starting at a certain preview is not an optimal way of choosing a starting position for an encode (especially in a CLI), it is fast, and flexible. By altering the number of previews to scan with --previews, it is possible to start an encode at any percentage of the video.
