KNN classifier save seems capped at around 4000 examples

→ Description 📝

I either found a bug 🐛 or the KNN classifier save is capped at around 4000 examples intentionally.

→ Helpful Information 🦄

I am generating my own data for the KNN classifier by making new examples, knnClassifier.getCountByLabel(); holds more than 4000. But the save file stays about the same as before the new examples and the amount of examples are not increased when I load the new model.json. So it can only save 4000 examples perhaps?
