/**
* Converts an ndarray buffer to a generic array (which may include nested arrays).
*
* @param {(ArrayLikeObject|TypedArray|Buffer)} buffer - data buffer
* @param {NonNegativeIntegerArray} shape - array shape
* @param {IntegerArray} strides - array strides
* @param {NonNegativeInteger} offset - index offset
* @param {string} order - specifies whether an array is row-major (C-style) or column-major (Fortran-style)
* @returns {(EmptyArray|Array|Array<Array>)} array (which may include nested arrays)
*
* @example
* var buffer = [ 1, 2, 3, 4 ];
* var shape = [ 2, 2 ];
* var order = 'row-major';
* var strides = [ 2, 1 ];
* var offset = 0;
*
* var out = ndarray2array( buffer, shape, strides, offset, order );
* // returns [ [ 1, 2 ], [ 3, 4 ] ]
