This module contains a small helper, which is used by the

:class:`btrfs.ctree.FreeSpaceBitmap`. It's also used by the
:func:`~btrfs.ctree.FileSystem.free_space_extents` convenience method of a
:class:`btrfs.ctree.FileSystem` object for generating a simple stream of free
space extent info transparently unpacking bitmaps.
