I’ve created a quirk for it, because my values also were all too high.

## Proposed change The Sonoff SNZB-02 sensor reports too high humidity values. …I compared to the newer SNZB-02D and Aqara Temperature/Humidity sensor. Those two are very close to each other in humidity values. The SNZB-02 is about 6% off in my messured environments Here is a screenshot before and after applying the quirk: <img width="1861" alt="Bildschirmfoto 2023-08-28 um 14 41 09" src="https://github.com/zigpy/zha-device-handlers/assets/1482002/3529ac60-248e-46b9-a489-ae4f18822f71"> ## Checklist - [x] The changes are tested and work correctly - [x] `pre-commit` checks pass / the code has been formatted using Black - [ ] Tests have been added to verify that the new code works
