fix(logging): initialize logging in logger file and move version log

[Lordmau5]

Another attempt at #104

I've moved the logging intialisation into it's own file logger.py
Then inside __init__.py I'm importing it and calling the method

I had to move out the version and debug prints into the main file or otherwise they would be printed on every sub-process creation

Running the following 2 commands yields these results:

python -c "import so_vits_svc_fork.__main__;from logging import getLogger;getLogger().info('hello')"
python -c "import so_vits_svc_fork.train;from logging import getLogger;getLogger().info('hello')"

Local test of poetry run pytest shows this:

I think the force-push messed up the CI test, can you re-run it?
