* Utility function to calculate a change hash for a `StoreItem`.
*
* @remarks
* This example calculates a change hash for an object that's been read in and then only writes it
* back out if it's been modified:
*
* ```JavaScript
* // Calculate state objects initial hash
* const hash = calculateChangeHash(state);
*
* // Process the received activity
* await processActivity(context, state);
*
* // Save state if changed
* if (calculateChangeHash(state) !== hash) {
* await storage.write({ 'botState': state });
* }
* ```
*
* @param item Item to calculate the change hash for.
* @returns change hash string
