Place d.ts files beside js files in build

[Sytten]

Hello!
I am trying to use some stuff that is not exported at the root (like in the ast file) and typescript can't find the type definition because they are in a different folder (types vs lib). Would it be possible to put them in the same folder like all other libraries.
Thanks :)

Can you also export RewriterOps, thanks!
