Support for python 3.11

Hi,

Looks like the pip install for python 3.11 is failing with the below error

Is it because there is no support for python3.11?

Please help me overcome this issue.

Thanks in advance.

```

まず Python 3.11 の pip install コマンドを再現し、拡張機能のビルド周辺にある setup.py、http_parser/http_parser.c、http_parser/parser.c を調査します。失敗の原因がパッケージの互換性にあるのか、開発用ヘッダー Python.h の不足にあるのかを確認し、その後、Python 3.11 でインストールが正常に完了することを検証します。
