Investigate fast-glob

The fast-glob project provides a stream interface. We should evaluate it against our API.

I created mrmlnc/fast-glob#373 and mrmlnc/fast-glob#374 based on our needs but haven't heard back.

Additionally, eslint just removed globby (which uses fast-glob) so we might not want to use it. We might actually use @nodelib/fs.walk and anymatch so our glob-stream implementation matches chokidar (people complain that the globbing isn't exactly the same).

fast-glob and fs.walk is dropping node 10 support, so we probably don't want to be using it. We can use a different walk library and anymatch.
