HTTP/3 Support over QUIC with Kwik (Feature Request)

Description

Hi there, and thanks for developing PowerTunnel!

Since the availability of http3, many sites offer their services in both the older HTTP/1.1 and HTTP/2 (which are TCP bases), and the newer HTTP/3 which uses UDP as for the transport layer.

This is both faster, and also not blocked by censorship agencies in many regions. Meaning it'd possible to bypass censorship by using the QUIC transport protocol. This is because the traffic on port 443 UDP is not being filtered in these regions the same as it's being done on port 443

Popular websites that use HTTP/3 include YouTube, Reddit, and all Cloudflare-based domains.

Currently there are no proxy software that support making http/3 requests, so since PowerTunnel is already doing MITM in order to figure out the outgoing request, it can forward it over Kwik, a pure Java-based QUIC implementation in order to make http/3 requests. Additionally, it can allow incoming http/3 requests as well with Kwik since it supports both QUIC requests and being run as a server.

This will lead to significant performance boosts if the website supports the HTTP/3 protocol, and an easier censorship bypassing in regions where the UDP traffic is not filtered.

Thank you, I'll check it later this month
