Added tests to verify Decompressor memory and ratio limits using real compressed data to simulate zip bombs.

  • Added test_memory_limit_with_real_data
  • Added test_ratio_limit_with_real_data
  • Added test_gzip_zlib_limits
  • Verified that default limits allow valid high-compression data (level 12), while strict limits correctly reject it.

PR created automatically by Jules for task 5272232841701043701 started by @404Setup

Added integration tests to `tests/security_limit.rs` to verify that `set_max_memory_limit` and `set_limit_ratio` correctly enforce limits on real compressed data. This ensures protection against zip bombs (highly compressed files) and excessive memory allocation requests across Deflate, Zlib, and Gzip formats.

Tests include:
- `test_memory_limit_with_real_data`: Confirms decompression fails when output exceeds `max_memory_limit`.
- `test_ratio_limit_with_real_data`: Confirms decompression fails when expansion ratio exceeds `limit_ratio` (using strict limit on level 12 compressed data).
- `test_gzip_zlib_limits`: Confirms limits apply to Gzip and Zlib streams.
