FIX: Move buffer to next location
When no output file is given save_stripes() should collect amount of stripes in passed buffer. Currently all stripes are saved in the same area in passed buffer. This causes that last stripe is returned on buffer begin only. Increase buffer (buf) pointer when save_stripes() is about switch to next stripe operation. This allows for proper buffer filling as input parameter length directs.
