Video Tracking SAM2

[dlangenk]

Explore if SAM2 does a better job in video tracking than the current opencv based implementation. Furthermore check if it is feasible to use SAM2 on larger videos or if they need to be chunked.

Using SAM2 would also mean that an automatic segmentation would come with it with all benefits and downsides.

A small test with the SAM2 online demo and the demo video. The tracking successfully stops when the object leaves the frame, but can be reinitiated.
