[C++] parquet::arrow::FileReader::GetSchema()

[asfimport]

The class has 

  /// \brief Return arrow schema by apply selection of column indices.
  /// \returns error status if passed wrong indices.
  ::arrow::Status GetSchema(const std::vector<int>& indices,
                            std::shared_ptr<::arrow::Schema>* out);

but not a GetSchema() that would return the schema for all the columns, the underlying implementation has it though.
