UDP-heavy app performance issues? (not surprising, so more of a "feature suggestion" than a bug report)

[tonsimple]

Hello!
First, thanks for great work on this plugin.

My (not unexpected) problem is that it is hitting a UDP intensive piece of software I run over shadowsocks pretty heavily.

Based on its operation description and the fact that I get mostly same issues if I run said piece of software over OpenVPN in tcp mode I infer that it is due to UDP->TCP->etc.

Could the plugin be modified to use QUIC(like) obfuscation for UDP part of shadowsocks traffic as an option?

QUIC is essentially UDP, backed by google and thus should not compromise the "decoy website" aspect of this plugin too much (and if someone is concerned by that, well, make it optional)

There already is a quic-only plugin for shadowsocks https://github.com/shadowsocks/v2ray-plugin but it sadly lacks the great "pretend to be a website" functionality
