v2.0.0-beta.5

Pretty big changes under the hood this time

All the different thresholds and "meters" under the plant device are now converted to number.* and sensor..
This should not really have much impact on the use of the integration, but it means that you might have to modify scripts or automations if you previously read the different plant. entities in there.

I am quite sure some bugs might have snuck in at the same time...
