Dask Pipelines

This package needs to be ported to the new API (bob.bio.base!180 (merged)).

The job is extremely easy, though. I short we need to:

• Wrap all the preprocessors and extractors from here (https://gitlab.idiap.ch/bob/bob.bio.vein/-/tree/master/bob/bio/vein/configurations) to their corresponding transformers https://gitlab.idiap.ch/bob/bob.bio.base/-/tree/dask-pipelines/bob/bio/base/transformers
• Wrap all the algorithms from here https://gitlab.idiap.ch/bob/bob.bio.vein/-/tree/master/bob/bio/vein/configurations using this https://gitlab.idiap.ch/bob/bob.bio.base/-/blob/dask-pipelines/bob/bio/base/pipelines/vanilla_biometrics/legacy.py#L183
• Wrap all the databases from here https://gitlab.idiap.ch/bob/bob.bio.vein/-/tree/master/bob/bio/vein/configurations using this https://gitlab.idiap.ch/bob/bob.bio.base/-/blob/dask-pipelines/bob/bio/base/pipelines/vanilla_biometrics/legacy.py#L39

This will get 95% of the task done. The other 5% are minor adjustments with documentation, extra test cases, and possible bugs that might be risen

Is anyone willing to help?
