Trackers 2.1.0 release

[SkalskiP]

Changelog

Warning

Starting with version 2.1.0, Trackers package drops support for Python 3.9. If your environment still relies on Python 3.9, stay on Trackers 2.0.x or upgrade your Python runtime to 3.10 or newer.

Warning

Starting with version 2.1.0, the Trackers package drops support for DeepSORTTracker and ReIDModel. We plan to bring back improved ReID support in future releases.

🚀 Added

Added support for ByteTrack, a fast tracking by detection algorithm focused on stable identities under occlusion. We evaluated both SORT and ByteTrack implementations on three standard multiple object tracking benchmarks, MOT17, SportsMOT, and SoccerNet Tracking.
