[CPP].Does the CPP version support append writing?

[t59688]

Does the C++ version support appending to files? I haven't found any examples of appending in the test and sample code; it seems like the file is deleted and recreated each time, whereas the Java version does support appending。

C++

int TsFileWriter::open(const std::string &file_path, int flags, mode_t mode) {
    if (check_file_exist(file_path)) {
        return E_ALREADY_EXIST;
    }

java

    try (ForceAppendTsFileWriter fwriter = new ForceAppendTsFileWriter(f)) {
      fwriter.doTruncate();
      write(fwriter);
    } catch (Exception e) {
      LOGGER.error("ForceAppendTsFileWriter truncate or write error ", e);
    }
  }

Currently, it is not supported, but it will be in the future. All features implemented on all Java versions will eventually be implemented on the CPP version.
