Update and simplify addon

[mansona]

This update should make the addon significantly simpler to contribute to and will also help solve a few of the issues that have been recorded.

I will be releasing this as a pre-release to help people test their applications before we release a new major version 👍

Hey anyone who is interested in checking out the next version 👋 you can now install the 5.0.0-0 pre-release using npm i ember-cli-notifications@next

This is a bit of a significant change in the build system but should not have changed the API too much. Please let me know if you have any issues and we can get them sorted before I release this new version

I am hoping to release this a week from today 👍

Hi @mansona

Thanks for this great work. I had been really waiting for this update to make our host application an Embroider compatible.

Anyway, It's been a month since you released this beta version. We have tested the beta and It works fine for us. Is there anything stopping you from merging the changes to the master? I'm eagerly waiting for the stable release to use this in our application.

Once again thanks for the great work!

Right folks, the time has come 🎉 I'm going to merge this as I'm confident that this has fixed most of the issues that people have been seeing.

Thanks for all the feedback and testing, and now we're starting the next chapter of this addon 💪
