This is the strided array equivalent of https://github.com/stdlib-js/stdlib/tree/develop/lib/node_modules/%40stdlib/iter/replicate, where each element is replicated a specified number of times.

API signatures:

greplicate( N, k, x, strideX, out, strideOut )
greplicate.ndarray( N, k, x, strideX, offsetX, out, strideOut, offsetOut )

where out is assumed to have N * k indexed elements.

Example output:

var x = [ 1, 2, 3, 4 ];
var out = [ 0, 0, 0, 0, 0, 0, 0, 0 ];

greplicate( x.length, 2, x, 1, out, 1 );
// out => [ 1, 1, 2, 2, 3, 3, 4, 4 ]
