I am looking for a way to convert from CONLL format NER annotations to the JSONL format used in Prodigy, to re-annotate a pre-existing dataset. I used the convert function in CLI for Spacy, but that does not seem to be useful for loading the annotations into Prodigy interface. Is there a pre-existing way to do this?

Edit: I found a ner.iob-to-gold in Prodigy recipes. However, that throws me the following error:

```python
C:\Users\svajjala\Downloads\Prodigy>python -m prodigy ner.iob-to-gold good_preds_premanual.iob

Sorry about this bug, and thanks for reporting it. It should be fixed in v5.1.
