Enable access to aliceVision logger initialization in python

[servantftransperfect]

This pull request introduces logging initialization for the AliceVision Python bindings, ensuring that the logger is set up at module import. The main changes are centered around exposing the logger configuration to Python and initializing it with a default verbosity.

Logging integration and initialization:

• Exposed a new function initialize_alicevision_logger to Python via SWIG, allowing the log verbosity level to be set from Python (src/aliceVision/system/System.i).
• Called system.initialize_alicevision_logger("info") during module initialization in src/aliceVision/__init__.py to set the default logging level and print a confirmation message.
