Support h2 and h2c

[domoritz]

I am building an application that makes lots of small requests and need really fast responses. HTTP/2 would be amazing for this and since I am already using the websocket implementation from here I would love to have support for HTTP/2 as well. I saw that you are planning HTTP/3 support but many browsers have not yet enabled HTTP/3 so having HTTP/2 today would be great.

I'm writing support for H2 and H3, already have a nice H2 parser in C but need to rework to merge it with uWS

Awesome to hear. I've really enjoyed using socketify.py for uwdata/mosaic#287 so far. The webscoket implementation is super fast but I hope the HTTP version can be much faster with HTTP2.

By h2, you mean https://python-hyper.org/projects/hyper-h2/en/stable/index.html, right? I see that it's pure python and wonder how that would perform to the current backend mostly in c++ (if I didn't miss anything).

By h2 I mean the h2 protocol it self: https://datatracker.ietf.org/doc/html/rfc9113
