Sometimes it is useful to access DTO's nested data by the means of JDK stream api

Any chance of this getting merged?

@NicklasWallgren Hi! As a workaround before merge, you could use lombok's @ExtensionMethod with these methods' implementations. Hope this will help you. Cheers!

Thanks for the reply. I've created a fork instead.

Thanks for the PR. There is another PR now (#68) which includes some more common methods as well. If that PR is merged, you could recreate this one and add your other methods.
