Foundation for a dataset (snapshot or, later, the main file) being a subset of the
truly collected images:
- JFJochReaderDataset gains source_image_number (image index -> original image
number; empty = identity).
- HDF5MetadataSource reads /entry/detector/number into that map and an inverse
(original -> local) map; FillPerImage / ReadSpots translate the requested global
image to this source's local index via ToLocalIndex (return nothing if the image
is not covered), so partial snapshots are correct and never read out of bounds.
- RegisterSnapshot now accepts a snapshot with fewer images than the dataset
(only rejects more), so sub-range / strided reprocessing runs register.
- The dataset-info plot draws each run at its original image numbers (x map from
source_image_number), so a subset run lands at the right place on the shared
axis. The live run's map is filled from msg.original_number.
This makes the foundation ready for strided / filtered selections (e.g. reprocess
only images with >N spots) without restricting to a min-max sub-range.
