     * This `metadata` file stores information about the potree cloud 2.0 in JSON format. the structure is :
     *
     * * __`version`__ - The metadata.json format may change over time. The version number is
     * necessary so that parsers know how to interpret the data.
     * * __`name`__ - Point cloud name.
     * * __`description`__ - Point cloud description.
     * * __`points`__ - Total number of points.
     * * __`projection`__ - Point cloud geographic projection system.
     * * __`hierarchy`__ - Information about point cloud hierarchy (first chunk size, step size, octree depth).
     * * __`offset`__ - Position offset used to determine the global point position.
     * * __`scale`__ - Point cloud scale.
     * * __`spacing`__ - The minimum distance between points at root level.
     * * __`boundingBox`__ - Contains the minimum and maximum of the axis aligned bounding box. This bounding box is cubic and aligned to fit to the octree root.
     * * __`encoding`__ - Encoding type: BROTLI or DEFAULT (uncompressed).
     * * __`attributes`__ - Array of attributes (position,  intensity, return number, number of returns, classification, scan angle rank, user data, point source id, gps-time, rgb).
