## Summary
Adds `class-as-data-structure` rule (`B903`). Also compare pylint's `too-few-public-methods` (`PLR0903`).
Took some creative liberty with this by allowing the class to have any
decorators or base classes. There are years-old issues on pylint that
don't approve of the strictness when it comes to these things.
Especially considering that dataclass is a decorator and namedtuple _can
be_ a base class. I feel ignoring those explicitly is redundant all
things considered, but it's not a hill I'm willing to die on!
See: #970
## Test Plan
