Create initial validation logic for configuration structs.

[Klaven]

We have a validation interface that should be implemented on all the configuration structs. Lets start with Stations and validate that the station has at least one step.

Initial implementation on Pipeline struct is here: Validation logic
pipeline's validate fn should be updated to call validate on sub stations

Please ask @Klaven if you have any questions!

Hey @Klaven!

Maybe I can give this one a go. I think I mentioned on Discord that I'm a Rust newbie but, if this is a good first issue, I'd like to work on it.

Any extra help is welcome!

@salasberryfin Sorry I was sick last week so I am behind on some things but 100% give it a try! if you would like help on it, ask during one of my streams and I would love to step you though what is there! I updated the issue to link to the current implementation that you can just add on to! Thanks for picking this up!
