malformed HTTP version "HTTP/2" when using rxss mode

[fuomag9]

Describe the bug

When using rxss mode and parsing a burp request file via the --cookie-from-raw option, dalfox will error out with malformed HTTP version "HTTP/2" if the request contains HTTP/2 instead of HTTP/1.1

Suggested fix is to allow parsing of HTTP/2 as well (it should not change anything in the request format regarding cookies)

Environment

• Dalfox Version: 2.7.5
• Installed from: go

Hi @fuomag9
This problem occurs because the http library itself used by dalfox is based on HTTP/1.1. It can be solved with HTTP2 support, but it's on hold because it's bigger than I thought 😭
