python 3.12 private directory requires __init__.py to avoid errors

[t3chap]

I installed PST on another computer without realizing that python 3.12 wasn't supported. I soon encountered the following error:

Private configuration private/private_config.yaml does not exist; no problem if running in sim mode
2024-04-30 01:15:19 DEBUG config {'type': 'config', 'stage': 'config'} Adding config defaults

                                             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
KeyError: 'object'

As the error message implies, a __init__.py file needs to be added in the private directory. In this file I simply put the word "pass".
Everything else seems to be working. I don't think this will break earlier versions and should probably be added to the repository.

Hope this helps someone.
