有关VoiceMessage的问题

虽然 commit https://github.com/cyanray/mirai-cpp/commit/c8f668dc0f736f0470c2a425217eeaaafcb20f18 修复了相关的代码，但是貌似这个commit https://github.com/cyanray/mirai-cpp/commit/625b96a20b7591314d0e8ec625cef159e9bdf2a2 又把有问题的部分加回来了

在VoiceMessage.hpp的ToJson()函数中 json result = { { "type", type_ }, { "voiceId", voiceId_.empty() ? nullptr : voiceId_ }, { "url", url_.empty() ? nullptr : url_ }, { "path", path_.empty() ? nullptr : path_ }, { "base64", base64_.empty() ? nullptr : base64_ }, { "length", length_ } }; 应改为 json result = { { "type", type_ }, { "length", length_ } };

完了，怎么会这样呢……
