chore(lib): Use brcast instead of createBroadcast

[vesparny]

Hi,

I've extracted the createBroadcast function into its own package.
https://www.npmjs.com/package/brcast
I use this patter a lot, so it made sense to me.

cheers

Hi @vesparny, thanks for the contribution. I wouldn't actually recommend using this pattern with React. When you broadcast stuff to circumvent sCU, you opt-out of the React paradigm and now you have to manage syncing state updates yourself. So I'm not really using or maintaining this package anymore. But thanks for the PR :)

yeah I see.
I meant that I use the createBroadcast pattern a lot outside of React apps.
