### Describe your change:

Disable unused dependencies in `requirements.txt` to try to reduce build times:
- Keras is a TensorFlow frontend, so I've also marked it as `python_version < '3.12'`. There's no reason to install Keras in every build when TensorFlow can't be used.
- projectq, scikit-fuzzy, and yulewalker are only used by broken (and thus disabled) files, so I've commented them out. If/when those broken files are fixed, we can uncomment them.
