onnx .dylib link [Mac M3/ARM/MACOS]

[farris]

Describe the bug
When following the steps to build the generate() API from source link, there is an issue linking the API back to the onnxruntime dependency

Traceback (most recent call last):
  File "onnxruntime-genai/examples/python/phi3-qa.py", line 1, in <module>
    import onnxruntime_genai as og
  File "/.venvs/universal_venv/lib/python3.12/site-packages/onnxruntime_genai/__init__.py", line 9, in <module>
    _dll_directory.add_onnxruntime_dependency(__id__)
  File "/.venvs/universal_venv/lib/python3.12/site-packages/onnxruntime_genai/_dll_directory.py", line 62, in add_onnxruntime_dependency
    raise ImportError("Could not find the onnxruntime shared library.")
ImportError: Could not find the onnxruntime shared library.

Expected behavior
To fix it, I changed the _dll_directory script to point to the onnx dylib

target_lib_path = "~/Desktop/dev/onnxruntime-genai/ort/lib/libonnxruntime.dylib"

Additional context
Do with this info what you will 😄

Hi @farris, the current version of GenAI doesn't have full support on macOS. I'm working on improving this and it should be improved in the next release. Thanks for trying it out :)
