Detailed Description

Router for segmentation_images (read-only).

Each entry is a per-frame semantic label raster keyed by sensor-frame node_id. The in-memory format is CV_32S with -1 for background and 0+ for class ids.

Handles paths like:

• labels → list all node_ids (JSON array)
• labels.<id> → PNG of the raster, stored CV_16U +1 offset (background = 0). Use .metadata for headers.
• labels[N] → same as above, by index
• labels.<id>.metadata → JSON with node_id, width, height, num_classes
• labels.<id>.image → PNG of the raster (same as default)
