Cannot validate typing of nested TypedDict having a NotRequired clause in Python 3.11

[frallain]

I want to validate a dictionary with a key whose value is another dictionary. Therefore, I have a parent TypedDict with a key targeting another TypedDict.

The thing is, I am using the NotRequired clause, which is available in Python 3.11 natively. (see https://peps.python.org/pep-0655/#usage-in-python-3-11 )

But trying to validate this dict with this configuration gives me the following import error:

Traceback (most recent call last):
  File "/app/script.py", line 7, in <module>
    from strongtyping.strong_typing import match_class_typing
  File "/usr/local/lib/python3.11/site-packages/strongtyping/strong_typing.py", line 14, in <module>
    from typing_extensions import NotRequired, Required
ModuleNotFoundError: No module named 'typing_extensions'

Python Version used Python 3.11.1 (main, Dec 8 2022, 00:05:00) [GCC 10.2.1 20210110] on linux

Package Version used strongtyping==3.10.3

Addon in use strongtyping_modules [yes/no] : no

To Reproduce Steps to reproduce the behavior:

1. Run a container of this docker image python:3.11.1

   docker run -it --rm python:3.11.1

2. In this container, install the following :

   pip install strongtyping==3.10.3

3. In this container, run the following script:

   
   from typing import TypedDict, NotRequired
   from strongtyping.strong_typing import match_class_typing

@match_class_typing class ChildType(TypedDict): key_a: int key_b: int

@match_class_typing class ParentType(TypedDict): child: ChildType not_required: NotRequired[int]

parent = {"not_required": 3, "child": {"key_a": 1, "key_b": "2"}} ParentType(parent)

**Expected behavior**
Should exit without error.

**Desktop (please complete the following information):**
 - OS: 
 ```bash
$ uname -a
Linux ab90f1fc83ca 5.13.0-25-generic #26~20.04.1-Ubuntu SMP Fri Jan 7 16:27:40 UTC 2022 x86_64 GNU/Linux

This time, this is not an edge case, Python 3.11 should be taken into account in the way strongtyping import NotRequired and Required. Thanks again for your work!

I wanted to release a specific version for >3.11 where I drop the import of typing-extension. If you have time could you maybe try it out https://github.com/FelixTheC/strongtyping/tree/py_3_11 if everything works like expected I will create a release for it.
