Deprecations - `exc.verifier` is deprecated in favor of `qq.verifier`.
Features - `qq.need_verify` is added to check if verification is needed. If `True`, `qq.verifier.fetch_image()` and `qq.verifier.verify(code)` is available.
1.1.0
- fix: verify code - fix: qzone feed
Breaking changes - `exc.verifier.image` is replaced with `exc.verifier.fetch_image()`. By calling `exc.verifier.fetch_image()` repeatedly, new verify codes will be received.
