/**
* Return a read-only view of an input ndarray where the dimensions of the input ndarray are expanded to a specified dimensionality by spreading dimensions to specified dimension indices and inserting dimensions of size one for the remaining dimensions.

* @example
* var ndarray = require( '@stdlib/ndarray/ctor' );
* var ndarray2array = require( '@stdlib/ndarray/to-array' );
* var spreadDimensions = require( '@stdlib/ndarray/spread-dimensions' );
*
* var buffer = [ 1.0, 2.0, 3.0, 4.0 ];
* var shape = [ 2, 2 ];
* var strides = [ 2, 1 ];
* var offset = 0;
*
* var x = ndarray( 'generic', buffer, shape, strides, offset, 'row-major' );
* // returns <ndarray>[ [ 1.0, 2.0 ], [ 3.0, 4.0 ] ]
*
* var y = spreadDimensions( 5, x, [ 1, 3 ] );
* // returns <ndarray>[ [ [ [ [ 1.0 ], [ 2.0 ] ] ], [ [ [ 3.0 ], [ 4.0 ] ] ] ] ]
