Supporting 425 Too Early

[pvichivanives]

I was wondering if there was a reason reqwest don't support HTTP response status code 425 too early:

RFC Here: https://datatracker.ietf.org/doc/html/rfc8470

If this seems reasonable to add I'm happy to go through the code and raise a PR for this.

I read through the RFC. Before writing code, what exactly would you hope it would do?

I would assume the relevant part is

Clients that use early data MUST retry requests upon receipt of a 425
(Too Early) status code; see Section 5.2.

So the question is whether reqwest supports early data

Honestly, I was thinking of adding a reqwest::StatusCode::TOO_EARLY just to add an easy way for users to deal with it in case the server mistakenly returns it (I'm assuming that reqwest doesn't support early data or else this status code would already exist). Looking at it again today though, I just noticed that this was a re-export of HTTP StatusCode so maybe I'm making this request in the wrong place?
