__contains__ return value for EmptySpecifier and AnySpecifier mixed up?

[felixp98]

First of all, thank you for this great library!

I stumbled across the following behaviour:

'1.0.0' in EmptySpecifier()
>> True
'1.0.0' in AnySpecifier()
>> False

src/dep_logic/specifiers/special.py:

class EmptySpecifier(BaseSpecifier):
    # other code deleted for readability

    def __contains__(self, value: str) -> bool:
        return True

class AnySpecifier(BaseSpecifier):
    # other code deleted for readability

    def __contains__(self, value: str) -> bool:
        return False

I'm wondering whether this is correct, because an empty specifier, as the name suggests, shouldn't contain any version and therefore return always False?
On the other hand the AnySpecifier should, as the name suggests, contain any version and therefore always return True?

Is a release planned in the coming days or weeks?
Otherwise, I would appreciate it if you could release a version 0.5.1 soon, as my script depends on this change.
