Support ESLint 7.x

[MichaelDeBoey]

ESLint v7.0.0 is released 🎉

It would be awesome to have official ESLint 7 support. 👊
I'm happy to help where I can of course 🙂

@MichaelDeBoey I haven't kept up to date on changes in ESLint 7. Do you know of any specific incompatibilities that we might run into here?

[MichaelDeBoey]

@benkimpel All changes can be found here and here.

Thanks @MichaelDeBoey. That's perfect. I'll evaluate our status this week... probably towards the end of the week. Lots going on at the moment!

Any way to progress this PR?

@weyert Like I said yesterday (#89 (comment)): #89 is good to be merged 🙂
