ONNX version restriction forces wheel build from source

[marc-weber-cultivated]

Completely unable to install hummingbird-ml due to this line:

hummingbird/setup.py

Line 25 in eb0a235

"onnx<=1.16.1",

ONNX no longer provides a prebuilt windows wheel for version 1.16.1, and the build fails due to a gigantic cmake error.

Hummingbird works totally fine if I just clone the repository, reference the python files and install ONNX 1.20.1.

Thanks for bringing this up. I can try to see if upgrading ONNX to 1.20.1 solves the issue
