Plugin enhancement: Ability to add dashboard filter on click of deckGL polygon

[mdshamoon]

SUMMARY

DeckGl polygon has an onclick function that emits a filter event. This doesn't seem to work as expected on the latest master and we were getting some errors. With these changes I have added the ability to setData mask (a filter at dashboard level). I have made the changes based on what I understood of the plugin directory structure. I would be really helpful if you can verify these changes or guide me on how to add dashboard level filters with DeckGL polygon.
