Failure of can_validate on non-generic _SpecialGenericAlias objects.

[sg495]

The can_validate function fails when called on _SpecialGenericAlias objects without a generic type specified.

>>> from typing_validation import can_validate
>>> from typing import Iterable
>>> can_validate(Iterable)
Traceback (most recent call last):

TypeError: '_SpecialGenericAlias' object is not iterable

The issue is in the _recorded_type and _repr methods of TypeInspector:

class TypeInspector:
    def _recorded_type(self, idx: int) -> typing.Tuple[Any, int]:
        # ...omitted...
        if tag == "type":
            if isinstance(param, type):
                return param, idx
        # ...omitted...
    def _repr(self, idx: int = 0, level: int = 0) -> typing.Tuple[typing.List[str], int]:
        # ...omitted...
        if tag == "type":
            if isinstance(param, type):
                return param, idx
        # ...omitted...

The condition isinstance(param, type) should be replaced with not isinstance(param, tuple).
