Log out in goal completion or error.

## What do you need help with?
How do I tell Baritone to log out when completing or erroring a goal?

I'm aware that "disconnectOnArrival" exists, but I'd also like a similar option, but for other operations, like `sel cleararea`.

Does such an option exist, or any other means to achieve this? I tried finding one but couldn't.

## Final checklist
- [x] I know how to properly use check boxes
- [X] I have not used any OwO's or UwU's in this issue.
