feat: remove next/express dep

[maraisr]

This removes the next "dev dep", that would caused non next users typing to fail, or for those not using express having potentially incompatible typing.

This I believe is a phase 1 of 2, seeing as both Express and Next extend the native http interface we could simply just do away with their magic wrapper methods, like json and redirect and implement those ourselves, meaning server's like Polka could also make use of this, and not have to expose those methods.

Here is an image proving typings still work:

This errors on the passport.use call now 😢 Any ideas how to fix this?

I can take a look at this. I think its the Record, which isnt quite compat with an object. I think i may need to make query be any, and not type it as strongly. Ill send up another PR shortly.

Further that, can you tell me why you're using util's inherit method, and not just a class extend?
