- **Usage**:
  ```python
  from pureapk import APKBuilder, sign_apk, align_zip_entry

  # Build an APK completely in pure Python
  builder = APKBuilder("MyApp.apk")
  builder.add_file("AndroidManifest.xml", manifest_bytes)
  builder.add_file("classes.dex", dex_bytes)
  builder.build()

  # Sign APK with v1 + v2 schemes
