Deobfuscate

cd reference
npm install
npm run deobfuscate

Or: node deobfuscator.js tags.js tags_deobfuscated.js

After DataDome updates their script, re-fetch, deobfuscate, then diff against the previous tags_deobfuscated.js and update ../go/internal/builder and ../go/internal/crypto if signal order or encryption changed.
