RUSTSEC-2022-0022: Parser creates invalid uninitialized value

[github-actions]

Parser creates invalid uninitialized value

Details
Status	unsound
Package	hyper
Version	0.10.16
URL	hyperium/hyper#2545
Date	2022-05-10

Affected versions of this crate called mem::uninitialized() in the HTTP1 parser to create values of type httparse::Header (from the httparse crate).
This is unsound, since Header contains references and thus must be non-null.

The flaw was corrected by avoiding the use of mem::uninitialized(), using MaybeUninit instead.

See advisory page for additional details.
