/**
* Applies a function to each nested element in a five-dimensional nested array and assigns the result to a nested element in a new five-dimensional nested array.
*
* ## Notes
*
* - The applied function is provided the following arguments:
*
* - **value**: array element.
* - **indices**: current array element indices.
* - **arr**: input array.
*
* @param {ArrayLikeObject<ArrayLikeObject>} arr - five-dimensional nested array
* @param {Function} fcn - function to apply
* @param {*} [thisArg] - function execution context
* @throws {TypeError} first argument must be a five-dimensional nested array
* @throws {TypeError} second argument must be a function
* @returns {ArrayArray} five-dimensional nested array
*
* @example
* var naryFunction = require( '@stdlib/utils/nary-function' );
* var abs = require( '@stdlib/math/base/special/abs' );
*
* var arr = [
* [ [ [ [ -1, -2, -3 ] ] ] ],
* [ [ [ [ -4, -5, -6 ] ] ] ]
* ];
*
* var out = map5d( arr, naryFunction( abs, 1 ) );
* // returns [ [ [ [ [ 1, 2, 3 ] ] ] ], [ [ [ [ 4, 5, 6 ] ] ] ] ]
