[BUG] Import error with python <= 3.9

[champystile]

Describe the bug
When importing pycatia with python 3.9, it raises a TypeError due to an annotation syntax introduced in python 3.10 :

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "C:\...\lib\site-packages\pycatia\__init__.py", line 21, in <module>
    from pycatia.base_interfaces.base_application import catia_application as catia
  File "C:\...\lib\site-packages\pycatia\base_interfaces\base_application.py", line 5, in <module>

  File "C:\...\lib\site-packages\pycatia\cat_logger.py", line 9, in <module>
    def has_level_handler(logger: logging.Logger | None):
TypeError: unsupported operand type(s) for |: 'type' and 'NoneType'

To Reproduce
With python 3.9 and pycatia 0.6.6, import pycatia :

import pycatia

Expected behavior
No exception :)

Desktop (please complete the following information):

• OS: Windows 11
• CATIA V5 version: rCxR1 (?)
• pycatia version: 0.6.6
• python version: 3.9.18

Additional context
Known solution: replace logging.Logger | None by Optional[logging.Logger] in the file cat_logger.py, line 9

Thanks for reporting this. I'll try and get this done this week.

Closing as 0.6.7 now has these changes implemented.
