Remove show_all_warnings

[badcode6]

🐛 Bug

if you try to install aim through metaseq, it crashes installing this package. Cython says: ValueError: got unknown compilation option, please remove: show_all_warnings

To reproduce

git clone the metaseq repo, cd metaseq, pip3 install . OR just install the gz for aim provided on pypi

Expected behavior

aim installing normally

Environment

• Aim Version (e.g., 3.0.1) 3.12.0
• Python version 3.8
• pip version 20.0.2
• OS (e.g., Linux) Ubuntu WSL2
• Any other relevant information

Additional context

go to setup.py:183, change it to return cythonize(extensions), everything is fine
