VectorizedParquetReader.FileIterator.close()closed the model then the reader without a try/finally, so ifmodel.close()threw, the underlyingParquetFileReaderand its input stream leaked. This closes the reader with try-with-resources so it is always released, and adds a test for the case where the model fails to close.
