(int64 * int32 * int64 ref * int64 Qcow_types.Cluster.Map.t) Lwt.tDecodes QCOW header and tables from the beginning of the stream, constructing a map of data clusters. Returns (virtual_size, cluster_bits, last_read_cluster, data_cluster_map)

unitstream_decode ?progress_cb ?header_info fd output_path decodes the input QCOW stream from fd, writing out the raw file to output_path.
Accepts header_info returned by start_stream_decode if the header has already been parsed separately (to determine the virtual size, for example).
If provided, progress_cb is a callback that will be called with integer percentage values representing copying progress.
