* Create entropy-scan.yml Found this tool by sheer luck? Let's see what it reveals! * Create compute-entropy.py make it beautiful * Create entropy-beauty-scan.yml the yml for entropy + beauty scanning * Delete .github/workflows/entropy-scan.yml delete the previous half-finished scanner * Update entropy-beauty-scan.yml try fixing merge issue postback
