    Add device sector size to partition object
    
    The device sector size is needed in all calculations that convert
    between sectors and bytes.  The device sector_size is included in
    the partition object because this object is used to contain
    operation information in addition to actual partitions and
    unallocated space.  A second option was considered to pass the
    device object to many methods, but this was considered a much
    larger task that might not provide significant gains in
    maintainability.
