Add helper methods to Glob instance

[Vaughan Rouesnel]

const glob = new Glob
glob.sync()

await glob()

not sure what you mean here?

If you create and instance of Glob, can you use it with promises.

Originally I thought you could attach events if you created an instance of glob, but it seems you can only listen for match, end and error events. So maybe not useful anymore.
