I've copy pasted this sample code from the example (https://github.com/xitongsys/parquet-go/blob/master/example/convert_to_json.go) and tried to read a file but got an error at the last line:

	reader, err := reader.NewParquetReader(fw, schema, 1)
	require.NoError(t, err)

	num := int(reader.GetNumRows())
	require.Equal(t, 2, num)

	data, err := reader.ReadByNumber(num)

runtime error: index out of range [1] with length 1

I can open this file by another application though.
