Do you have any proxy servers that require authentication support? #30

I use my own proxy server to access the OpenAI interface, but my proxy server requires authentication. However, I do not know how to set the authentication information for the current interface, so I received the following error message:

I have added two parameters: proxyUsername and proxyPassword. You can try them out (I don't have the environment to test them). Here's how to use them:

var llm = OpenAI.builder()
        .openaiOrganization("xxx")
        .openaiApiKey("xxx")
        .openaiProxy("http://host:port")
        .proxyUsername("xxx")
        .proxyPassword("xxx")
        .requestTimeout(16)
        .build()
        .init();
