Add option to look only for certain file extensions

[jantimon]

We use a shared repository with our backend team and we would have to ignore backend files and assets.

Can we have something like prettier --write \"**/*.*(js|jsx|json)\" for prettier-quick?

So it would check only staged files that actually match the minimatch pattern?

Would it work if you just add the files you want to ignore to .prettierignore?

Would be nice if pretty-quick and prettier are working in the same way.

`pretty-quick --staged "**/.(js|jsx|json)``

and THANK you for this project 👍

I prepared #59 which adds patterns - could you please take a look if that works for your?
