Can `step_knnimpute` be parallelized?

[johanneswaage]

Right now, step_knnimpute uses only one thread, and can take a long time for datasets with a large number of features. Could threads be passed to the underlying distance function for any gains?
Thanks

The underlying function has an option for threading. I'll add a options argument so that you can pass options to gower::gower_topn().
