Splits large image sets into overlapping chunks of 20 images
(5 image overlap between chunks). Each chunk runs cpfind + cpclean
independently, then CPs are merged with remapped global indices.
Avoids O(n^2) explosion:
- 80 images monolithic: cpfind ~30min + cpclean ~70min = ~100min
- 80 images in 4 chunks of 20: ~4x(2min + 0.5min) = ~10min estimated
