Add maxdailygust, indoor feelsLike/dewPoint, and Ambient rain accumulators

- Max Gust Today tile (maxdailygust from Ambient)
- Feels Like In tile (feelsLikein, Ambient-computed)
- Use Ambient's dewPointin directly instead of computing from tempinf/humidityin
- Event Rain tile (eventrainin, shows only when > 0)
- Total Rain lifetime tile (totalrainin)
