FEATURE: Start using Never as return types for disallowed operations

[Dr-Irv]

See #432 where methods were added to TimestampSeries and TimedeltaSeries that return Never, which pyright will pick up as invalid.

We could add more of these to disallow certain operations between incompatible types, and then use the TYPE_CHECKING_INVALID_USAGE pattern to check for these.

[Dr-Irv]

Turns out that we should not do this. See discussion here:
python/mypy#14424

If you have a base class Base and a subclass Sub, then just declare the valid parameters for a method in Sub. This will override any declaration in Base. For mypy, probably need # type: ignore[override].

If you have a method xyz(self, x: Any) in Base and you don't want to allow Sub to be called then add def xyz(self, x: Never) -> Never in Sub, or in Sub, you can write xyz = None.
