Rule request

"WPS600 Forbid subclassing lowercase builtins" should allow the following

class PizzaToppings(str, Enum):
    MARGHERITA = "MARGHERITA"
    MARINARA = "MARINARA"

Thesis

Enums are a bit akwkard in Python. The class PizzaToppings(str, Enum):... construct allows to create what is basically a string equivalent of IntEnum, so that one can do

if current_topping == PizzaToppings.MARINARA:
    ...

Reasoning

It seems beneficial, farily widely used, and has no negative side effects I can think of. No reason to ban it.

Thanks.
