Drop unlabeled records in dataset

[pyested]

Hi! Thanks for the nice extension. I was wondering if it is possible to drop the unlabeled records in a dataset using datatools. I have a dataset with both labeled and unlabeled records, and I just want to keep the labeled ones. I can do this with pandas, of course, but I would like to know if it is possible to use datatools to do it and integrate it in my workflow.

Thank you for using ASReview!!

Datatools is designed to host some useful code before it is integrated into ASReview itself, and your suggestion is a good example, see this PR: asreview/asreview#1335. The current API allows for some data managing: https://asreview.readthedocs.io/en/latest/generated/asreview.Dataset.html. And in the upcoming v2 release it will be even more easy, right @J535D165?
