Bring back Just the Rallies exports!

While PB Vision already removes dead time when analyzing rallies, the full-length video still includes time between points during playback. It would be helpful to have an option that lets users watch a version of the video where all downtime between rallies is trimmed out — making the match easier and faster to review. This would be especially useful for coaches and players looking to focus on gameplay-only footage.
