Add expandDirectories option and set nodir to true by default

[kevva]

Noticed a pretty large performance regression so might have to fix that first before merging. Would've liked to to implement the login in generateGlobTasks but we'd need to introduce generateGlobTasksSync in that case.

Fixes #33.

Ok, think I've nailed the performance regressions to the nodir option being true, and the isDirectory call here https://github.com/kevva/dir-glob/blob/0a3b078f088836d9584510d1c735875dac9dc98b/index.js#L45.

I'm wondering if we maybe should check if it's a glob using a regex before checking if it's a directory in the dir-glob module?

Temporary?

[kevva]

Yes, that branch hasn't been merged to master yet.

It's hard to reliably do that. Let's skip that for now. I don't want to deal with the headache of false negatives.

Looks good! Glad we could finally include this in globby 😎
