Summary

IMDB has started returning HTTP 202 responses with AWS WAF challenges instead of page content.
This PR adds automatic challenge solving so the library continues to work transparently.

Changes

  • New Aws.php: PHP port of the AWS WAF challenge algorithm (AES-GCM encryption, CRC fingerprinting, bandwidth/scrypt/PoW solvers). Based on tveronesi/imdbinfo (MIT License).
  • Modified Request.php: Detect 202 status, fetch challenge HTML, solve via Aws, retry with token cookie. Token is cached to avoid re-solving on every request.
  • composer.json: Added ext-openssl requirement.
  • bootstrap.php: Added Aws.php autoload entry.

How it works

  1. Request gets HTTP 202 → solveAwsChallenge() is triggered
  2. If response body is empty (e.g. GraphQL API), challenge HTML is fetched from the main domain
  3. Challenge is solved and the token is sent as aws-waf-token cookie on retry
  4. Token is persisted to file (~280s TTL) so subsequent requests skip solving
