could dependency on onnxruntime be avoided?

[wtholliday]

I'm working on a port of NeuralNote to visionOS and hitting some trouble getting onnxruntime to compile for visionOS.

Comment here says that Features is doing a CQT (what does "harmonically stack" mean?). I was wondering if other CQT code could be used instead of the onnx model? For example: https://github.com/cannam/constant-q-cpp
