What happened?

I cloned master and went to run tests, but it's unable to compile s2n-quic-h3 for the core: http3-preview test set.

Additional Context

I believe one way to fix this, is to merge in upstream fix from aws/s2n-quic#2313 (comment) into https://github.com/SergioBenitez/s2n-quic-h3 and then update the revision in core/lib/Cargo.toml

References:

• (async) Remove or replace typed headers #1067 (comment) mentions this test problem
• s2n-quic 1.45 is semver breaking aws/s2n-quic#2313

Final Notes:

• This is my first issue for Rocket, so definitely point out any mistakes I've made
• This was on FreeBSD, but I believe this problem would still exist on other OSs

System Checks

• My bug report relates to functionality.
• I have tested against the latest Rocket release or a recent git commit.
• I have tested against the latest stable rustc toolchain.
• I was unable to find this issue previously reported.
