add curl's ANY and ANSAFE authorization options

Implements #1184

I actually wanted to refactor Session::SetAuth a bit to reduce code duplication. Not sure if that would be desired?

@hyOzd thanks! LGTM

What exactly are your plans?
If you got a good idea, you are always welcome to refactor it.
Nevertheless, I would suggest doing this in a follow-up PR if possible so we follow the rule, one PR per change.

void Session::SetAuth(const Authentication& auth) {
    long auth_flag;
    // Ignore here since this has been defined by libcurl.
    switch (auth.GetAuthMode()) {
        case AuthMode::BASIC:
            auth_flag = CURLAUTH_BASIC;
            break;
        case AuthMode::DIGEST:
            auth_flag = CURLAUTH_DIGEST;
            break;
        case AuthMode::NTLM:
            auth_flag = CURLAUTH_NTLM;
            break;
        case AuthMode::NEGOTIATE:
            auth_flag = CURLAUTH_NEGOTIATE;
            break;
        case AuthMode::ANY:
            auth_flag = CURLAUTH_ANY;
            break;
        case AuthMode::ANYSAFE:
            auth_flag = CURLAUTH_ANYSAFE;
            break;
    }

    curl_easy_setopt(curl_->handle, CURLOPT_HTTPAUTH, auth_flag);
    curl_easy_setopt(curl_->handle, CURLOPT_USERPWD, auth.GetAuthString());    
}

Something like that. But I don't think it is worth opening a separate PR.

Ah, I see. If you want, you can make a minimal PR with it. It would be a good amount of cleanup.

Else I will try to take care of it eventually.
