 * @assertion Stream<List<int>> openRead([int start, int end])
 * Create a new independent Stream for the contents of this file.
 *
 * If start is present, the file will be read from byte-offset start. Otherwise
 * from the beginning (index 0).
 *
 * If end is present, only up to byte-index end will be read. Otherwise, until
 * end of file.
 *
 * In order to make sure that system resources are freed, the stream must be
 * read to completion or the subscription on the stream must be cancelled.
