I noticed that in rare occasions, sanitizing a molecule could fail due to seemingly outdated usage of the logging module in _sanifix4.py. I propose to use the RDKit logger instead, because to me personally this code logically falls under RDKit and so that verbosity can be controlled through Datamol's dm.without_rdkit_log() context manager.

Example in which logging could go wrong:

import datamol as dm
import numpy as np
import autosklearn.regression

smi = '[NH4][Pt]([NH4])(Cl)Cl'
mol = dm.to_mol(smi, ordered=True, sanitize=False)
mol = dm.sanitize_mol(mol)  # This will throw the normal warnings as expected

X = np.random.random((100, 10))
y = np.random.random((100, 1))

# AutoML configures the logging module
obj = autosklearn.regression.AutoSklearnRegressor(time_left_for_this_task=30)
obj.fit(X, y)

mol = dm.to_mol(smi, ordered=True, sanitize=False)
mol = dm.sanitize_mol(mol)  # This will now throw a logging error

@hadim seeing how the codecov fails, I would be happy to add a test but it seems a bit silly to do so for these changes.

Codecov is not blocking here. Thanks!
