Conflicts in the three CPU pixel loops the fused pipeline split per block, resolved by carrying this
branch's loop bodies into the new functions with the per-pixel arithmetic unchanged:
- AdaptiveSpotFinderCPU: the register-held ring sums now live in AccumulateRingsBlock (stored at the
end of each block, so the additions stay in pixel order).
- ImagePreprocessorCPU::AnalyzeBlock reads the PixelMask-derived 32-pixel mask words at first + i.
- ImageSpotFinderCPU::DetectPass: rc173's new_row() marking/fill_row calls kept in place, the
vertical update replaced by the vectorised slide with the prev_strong fix-up.
Byte-identical p.hkl, p.mtz, p_P1.mtz, p_unmerged.mtz vs rc173 references on myob, cytc, lyso,
sparse (CPU-only build) and myob (GPU build); targeted tests (ImageSpotFinderCPU*, AdaptiveSpotFinder,
SpotFinding, PixelMask, Bragg*, RotationScale, AzimuthalIntegration, portable) pass.
