expose FromRequest and FromRequestParts macros in axum

[tamasfe]

I would expect to just #[derive(FromRequest)] if the macros feature is enabled, this tiny PR enables that.

Sure!

How does the docs look for this? Since you're exporting a proc-macro from a non-root module. Does that work?

Also, wanna add a note to the changelog as well?

[tamasfe]

The docs seem to be inlined so it's the same as in the axum-macros crate, the axum links work as well since they point to docs.rs.

I've added an entry to the changelog.

FWIW the changelog seems wrong - this somehow moved from "unreleased" to "0.6.0-rc.2" section

but 0.6.0-rc.2 doesn't have the derives yet:

@RReverser thanks for noticing. I pushed a fix in a57bd9a.
