Pydantic >2.0.* seems to result in problems

[maralasar]

Describe the bug
When running my code (can't post it here), I get an import error from filip as a site package installed in an venv!

  File "...", line 4, in <module>
    from filip.models.ngsi_v2.iot import ServiceGroup
  File ".../venv/lib/python3.7/site-packages/filip/__init__.py", line 4, in <module>
    from filip.config import settings
  File ".../venv/lib/python3.7/site-packages/filip/config.py", line 7, in <module>
    from pydantic import BaseSettings, Field, AnyHttpUrl
  File ".../venv/lib/python3.7/site-packages/pydantic/__init__.py", line 206, in __getattr__
    return _getattr_migration(attr_name)
  File ".../venv/lib/python3.7/site-packages/pydantic/_migration.py", line 280, in wrapper
    '`BaseSettings` has been moved to the `pydantic-settings` package. '
pydantic.errors.PydanticImportError: `BaseSettings` has been moved to the `pydantic-settings` package. See https://docs.pydantic.dev/2.0.2/migration/#basesettings-has-moved-to-pydantic-settings for more details.

I had to adjust some of the pathes in the error message, due to restricted information!

To Reproduce
Steps to reproduce the behavior:

1. pip install filip
2. run any code that imports BaseSettings from Pydantic (in my case it was ServiceGroup )

Environment (please complete the following information):

• OS: Windows 10
• Python-Version: 3.10, 3.9, 3.8, 3.7
• FiLiP-Version: 0.2.5

Additional context
In requirements.txt and setup.pythe version of pydantic is just defined using >= which is likely the cause. In pydantic v2.* there seems to be a change in the structure resulting in the ImportError above!
Maybe fixing it to pydantic~=1.10.11 (lastest v1 version) would solve the problem until v2 is more common!
At the moment in theory everyone installing filip into a new environment will end up with this error!
