* Splits a number into the high and low 32-bit words of a 64-bit unsigned integer and assigns results to a provided output array.

* @param {NonNegativeInteger} value - integer value in the range [0, 2^53-1]
* @param {Collection} out - output array
* @param {integer} stride - stride length
* @param {NonNegativeInteger} offset - starting index
* @returns {Collection} output array
*
* @example

* var out = new Uint32Array( 2 );
* // returns <Uint32Array>[ 0, 0 ]

* var w = assign( 9007199254740991, out, 1, 0 );
* // returns <Uint32Array>[ 2097151, 4294967295 ]
