Cleanly split or remove component and pipeline SDKs / extras

[RobbeSneyders]

With the introduction of the lightweight components, our component and pipeline SDKs are no longer cleanly split. We should either split them again, or include the optional installs for both in the default installation.

This is the error I currently get when trying to run a pipeline without any extras installed. The pipeline does not use a lightweight component.

(base) jupyter@download-images-small-eu:~/src$ fondant run local pipeline.py
