Converts a strided array to a four-dimensional nested array.

## Notes

-   The function assumes that the input array is compatible with the specified array shape, dimension strides, and index offset.

@param {Collection} x - input array
@param {NonNegativeIntegerArray} shape - array shape
@param {IntegerArray} strides - dimension strides
@param {NonNegativeInteger} offset - index of the first indexed value in the input array
@returns {Array<Array<Array<Array>>>} four-dimensional nested array

@example
var x = [ 1, 2, 3, 4, 5, 6 ];

var arr = strided2array4d( x, [ 1, 1, 3, 2 ], [ 6, 6, 2, 1 ], 0 );
// returns [ [ [ [ 1, 2 ], [ 3, 4 ], [ 5, 6 ] ] ] ]

@example
var x = [ 1, 2, 3, 4, 5, 6 ];

var arr = strided2array4d( x, [ 1, 1, 3, 2 ], [ 1, 1, 1, 3 ], 0 );
// returns [ [ [ [ 1, 4 ], [ 2, 5 ], [ 3, 6 ] ] ] ]
