method to set custom click listener / load data from an external source

[djkramnik]

Trying to use this library in a chrome extension, but needed a way to save data to chrome storage instead of localforage (for cross domain data storage). Created a few helper methods to enable this

• setClickListener
• clearClickListener
• loadData

Let me know if open to this, I can flesh this out with documentation / tests. I admit it's a very straightforward implementation but tried not to change too much of what was present.

Usage would be like this:

// loading data into regression model from user controlled source (i.e. chrome storage) 
chrome.storage.sync.get('webgazer_data', function(data) {
  webgazer.loadData(data);
  webgazer.setClickListener((event, {data}) => {
    // saving reg data to custom data source
    chrome.storage.sync.set('webgazer_data', data)
  });
  await webgazer.begin();
});

Has there been any progress on getting this accepted?
I would find this helpful as well.

I think it requires some testing from people who are interested in this. So please report back if you've tried it.
