Unify internal tracker container name across trackers (tracks vs trackers)

Hi, I noticed that the internal container for active track objects is not named consistently across trackers: SORTTracker uses self.trackers ByteTrackTracker uses self.tracks OCSORTTracker uses self.tracks Could this be unified into a single interface? This inconsistency makes it harder to build generic utilities on top of the library, because downstream code has to special-case different tracker classes just to access active tracks. It would be great to standardize on one attribute name (tracks or trackers) and possibly keep the old name as an alias for backward compatibility. Thanks for considering it.
