The offline entry point for a raster. It scores every image of a stored grid scan
- spot finding for the per-cell resolution, no indexing, because a raster answers
where the crystal is and not what its lattice is - hands the per-image protein and
ice scores to AnalyzeGridScan, and writes what came back as two files beside the
usual output: <prefix>_raster_report.txt in the idiom of the results report, and
<prefix>_raster.json with the same content typed, so a battery can aggregate a
sweep without scraping prose.
--beam-size states the beam at the sample, defaulting to the file's
incident_beam_size. It matters more than it looks: the reported crystal sizes are
measured and still contain the beam, and taking an anisotropic beam back out is a
subtraction of two covariance matrices, so a beam given as square when it is not
rotates the reported crystal axis. --raster-protein-threshold and
--raster-min-cells expose the two constants AnalyzeGridScan held at file scope, so
a sweep can vary them without a rebuild; they are now defaulted parameters with the
old values, and every existing call is unchanged.
The observer feeding the analysis reads the file's own image number
(DataMessage::original_number), not the loop's ordinal, so -s/-e/--stride cannot
silently shift the grid mapping.
