Integrate Hydration data in Health Connect

[PaulLesur]

Hello ! I love CaffeineHealth app 👌

I use somes apps to vizualize my health data stored in Health Connect. I can see the caffeine but there is no hydration data.

It would be a great thing to add Hydration data when you log a beverage in CaffeineHealth.
