Support HTTP/3

[moderation]

Consider supporting HTTP/3 (h3). The following projects implement h3 in Rust however Cloudflare's Quiche might be the better option as it doesn't require C projects (Mozilla's Neqo requires NSS) and can be compiled as a static musl binary. It looks like Quinn only implements HTTP.0.9 over QUIC

• https://github.com/cloudflare/quiche
• https://github.com/mozilla/neqo
• https://github.com/quinn-rs/quinn

ht uses reqwest, so that would need to support HTTP/3 first. That'll likely happen when hyperium/h3 is mature enough to be used by hyper.

reqwest support makes sense. The issue for HTTP/3 support in hyper is at hyperium/hyper#1818

The latest version of reqwest has added experimental support for HTTP/3 🎉

I tried to implement this feature, but there are some issues such as the need to set RUSTFLAGS='--cfg reqwest_unstable' environment variable, so I think it's better to implement this feature after the http3 feature of reqwest is stable.
