{{alias}}( arrays, shape, fcn )
    Applies a binary callback to elements in two three-dimensional nested input
    arrays according to elements in a three-dimensional nested mask array and
    assigns results to elements in a three-dimensional nested output array.

    An element in an input array is "masked" if the corresponding element in the
    mask array is non-zero.

    Parameters
    ----------
    arrays: ArrayLikeObject
        Array-like object containing two input nested arrays, an input nested
        mask array, and one output nested array.

    shape: Array<integer>
        Array shape.

    fcn: Function
        Binary callback.

    Examples
    --------
    > var x = [
    ...     [ [ 1.0, 2.0 ], [ 3.0, 4.0 ] ],
    ...     [ [ 5.0, 6.0 ], [ 7.0, 8.0 ] ]
    ... ];
    > var y = [
    ...     [ [ 1.0, 2.0 ], [ 3.0, 4.0 ] ],
    ...     [ [ 5.0, 6.0 ], [ 7.0, 8.0 ] ]
    ... ];
    > var m = [
    ...     [ [ 0, 1 ], [ 0, 0 ] ],
    ...     [ [ 1, 0 ], [ 0, 1 ] ]
    ... ];
    > var z = [
    ...     [ [ 0.0, 0.0 ], [ 0.0, 0.0 ] ],
    ...     [ [ 0.0, 0.0 ], [ 0.0, 0.0 ] ]
    ... ];
    > var shape = [ 2, 2, 2 ];
    > {{alias}}( [ x, y, m, z ], shape, {{alias:@stdlib/number/float64/base/add}} );
    > z
    [ [ [ 2.0, 0.0 ], [ 6.0, 8.0 ] ], [ [ 0.0, 12.0 ], [ 14.0, 0.0 ] ] ]
