TEMPORARY Detach from bob.bio.base

Hi guys,

We are about to have a beta release of bob.bio.base and bob.bio.face. Thanks to @ydayer, we'll have a very nice user-guide for both very soon.

The future bob.bio.base is very different from the current one (I'll let you dig here https://gitlab.idiap.ch/bob/bob.bio.base/-/tree/dask-pipelines and here https://gitlab.idiap.ch/bob/bob.pipelines) and this will impact a lot the current version of this package. That's why this issue.

Until we have this package ported to use bob.pipelines, I would like to move the content from the current bob.bio.base to a module in this package, hence, we can have a beta version of the new bob.bio.base without breaking this one.

What do you think?
