There is a code duplication in the [POS Processor source](https://github.com/stanfordnlp/stanza/blob/6e442a6199f7e466c57c02de8d2f9d516bdd5715/stanza/pipeline/pos_processor.py#L81) which is caused by not using the tqdm disable option. I suggest simply deleting the code duplication and providing `disable=not self._tqdm`.
