   .. code-block:: python

      def ufv_unstack(
              data:         typ.Tuple,  # (*supercores, shape, masks): n_supercores arrays, int-tuple, 4-tuple of masks
              n_supercores: int,        # 4 (frame) or 2 (variations)
      ):  # -> nested tuple (shaped like stack_shape) of unstacked bv .data leaves


   Unstack a (stacked) bv ``.data`` tuple into an array-like tree of unstacked ones (the WHOLE stack).

   The supercores and the four rank masks unstack along the stack axes ``1 .. len(stack_shape)``;
   ``shape`` is shared and replicated onto every leaf. Mirrors :py:func:`ut3_operations.ut3_unstack`;
   thin wrapper over :py:func:`ufv_unstack_axes` over the full stack.
