chore(iast): improve iast startup time

[avara1986]

Add these libraries to the IAST deny list:

• numpy
• allauth
• celery
• cv2
• pydicom
• nibabel
• scipy
• kombu
• greenlet
• redis
• PIL
• matplotlib
• amqp

Migrate deny list to a regex

If a project imports all those libraries, the startup time benchmarks are:

main branch:

Start: December 23, 2024 - 11.45:11.363
End: December 23, 2024 - 11:45:40
Django version 5.0.6, using settings 'showcase.settings'
Starting development server at http://127.0.0.1:8000/
