Annoying warning due to joblib

[oterrier]

When delft is used as a library in another python application using a more recent version of scikit-learn (0.22.2 for example) an annoying FutureWarning is dispayed:

FutureWarning: sklearn.externals.joblib is deprecated in 0.21 and will be removed in 0.23. Please import this functionality directly from joblib, which can be installed with: pip install joblib. If this warning is raised when loading pickled models, you may need to re-serialize those models with scikit-learn 0.21+.
  warnings.warn(msg, category=FutureWarning)

This is due to the explicit

from sklearn.externals import joblib

in sequenceLabelling/preprocess.py

Wich should be replaced by

import joblib

And at the same time it could be interesting to bump the current version of scikit-learn to a more recent one (0.22.2 for example)

Best regards
