Broadcast Channel API

The broadcast channel API does exactly what crosstab does, but better:

It has a 76% global coverage. https://caniuse.com/#search=BroadcastChannel

I'm sorry. My original comment was quite short.

Crosstab was created back in 2014 when the Broadcast Channel API simply did not exist. In the absence of modern web APIs, this project solved the need for communication between browsing contexts. Crosstab would now be better as a polyfill for the Broadcast Channel API for that remaining 24%. The README should be updated to at least mention that a new API exists.

@asms That certainly could be an option but you would have to rewrite the lib. To work like the Broadcast Channel API and there are already Polyfills so I don't really see the need to change this lib
