/**
* Applies a quinary callback to elements in five two-dimensional nested input arrays and assigns results to elements in a two-dimensional nested output array.
*
* ## Notes
*
* - The function assumes that the input and output arrays have the same shape.
*
* @param {ArrayLikeObject<Array<Collection>>} arrays - array-like object containing five input nested arrays and one output nested array
* @param {NonNegativeIntegerArray} shape - array shape
* @param {Callback} fcn - quinary callback
* @returns {void}
*
* @example
* var ones2d = require( '@stdlib/array/base/ones2d' );
* var zeros2d = require( '@stdlib/array/base/zeros2d' );
* var add = require( '@stdlib/number/float64/base/add5' );
*
* var shape = [ 2, 2 ];
*
* var x = ones2d( shape );
* var y = ones2d( shape );
* var z = ones2d( shape );
* var w = ones2d( shape );
* var v = ones2d( shape );
* var out = zeros2d( shape );
*
* quinary2d( [ x, y, z, w, v, out ], shape, add );
*
* console.log( out );
* // => [ [ 5.0, 5.0 ], [ 5.0, 5.0 ] ]
