Returns metadata for one or more las or laz point cloud/LiDAR files from a local file or directory source, optionally constraining the bounding box for metadata retrieved to the lon/lat bounding box specified by the x_min, x_max, y_min, y_max arguments.
Note: specified path must be contained in global allowed-import-paths, otherwise an error will be returned.
