Some types are not exported

[Pita]

Hi Reducto team,

Thanks for the great work on the library!

We’ve run into a small issue when trying to use some internal types like NotGiven, Headers, Query, and Body. Right now, we have to import them from reducto._types, which causes Pyright to throw type errors. To work around it, we're currently using # type: ignore, but it would be much cleaner and safer if these could be exported directly from the main reducto module (similar to how other types are exposed).

Here’s a quick example of what we’re doing:

from reducto._types import (  # type: ignore
    NOT_GIVEN,
    Body,
    Headers,
    NotGiven,
    Query,
)

# Used in a wrapper function like this:
async def extract_with_reducto(
    ...
    options: BaseProcessingOptions | NotGiven = NOT_GIVEN,
    ...
    extra_headers: Headers | None = None,
    ...
) -> ExtractResponse:

Would it be possible to make these types publicly available via the main module? It would help with cleaner type-checking and avoid the need for type: ignore.

Thanks again!
