Samautomaticmaskgenerator stops after finding around 70 segments in multiple images

*Edit*:
If you want more maskes / segmentations:

python3 amg.py --checkpoint ~/models/sam/sam_vit_h_4b8939.pth --input /home/user/image.png --output results/ --model-type vit_h --points-per-side 64

Start with the amg.py entry point and reproduce the reported behavior on multiple images using the command shown in the issue, including the specified checkpoint, model type, and points-per-side. Inspect how mask generation proceeds across inputs and compare the resulting segment count with the report; done means the stopping behavior is understood and the intended multi-image processing result is verified.
