points_read_xyz — FILEIO points op

• Data kinds: text → points

• Call: import fullseye as fs; fs.ledger.points_read_xyz(data) (to call the implementation directly, import fileio; fileio.points_read_xyz(data); from the registry, opsfileio.get("points_read_xyz"))

• GPU: none (CPU reference implementation only)

Usage

Read whitespace-delimited XYZ text and return (N,3) points.
