Dask client is created by user but stopped by vanilla-biometrics
Hello, Currently to use vanilla-biometrics one has to provide an already instantiated Dask client, which is closed by the vanilla-biometrics script at the end of the run. This gives the false impression that one can instantiate a Dask client in a Python script, and then use it for several successive vanilla-biometrics experiment, which is not the case. Should maybe the opening/closing of the Dask client be entirely handled either by the user, or by the vanilla-biometrics script ? In the latter case I guess some configuration dict for the client could be passed instead when calling vanilla-biometrics.
