Encoding bug
Created by: MAGLeb
- add import/export for "one_hot_encoding" operation
- whether categories in test data contain in train data
- fix issues with categorical expansion
- fix testing time
RIGHT now we have preprocessing pipeline:
- convert values to one type in columns
- fill missing values
- one hot encoding for categorical
