reduce dvc dependency

[kervel]

it should be possible to run these tools without having to run dvc.

• we should not count on dvc pipeline to only run stuff when inputs changed. Instead, the scripts should be the equivalent of a no-op when all data is already up to date.
• we should not rely on dvc parameters, or at least, make the reliance optional. we should be able to pass required classes on command line or as yaml file

we should need a proper CLI interface, with typer, click, or with something else (just getopt)
