Review Comment:
   @islamismailov, the first call to init, the `ReadConf` is copied and stored 
in the `ParquetReader` for future use. But the `ReadConf` that was just created 
is the one that is returned. That way the first init call uses the same stream 
for the `FileIterator` and doesn't reopen one.
