Add structure to CellDetails

[MK-2001]

Describe the bug
Currently all Temps / Volts are within one folder in ioBroker.Objects are listed down. For my behavior it is uncomfortable to review these values and determine which module is affected.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Objects'
2. Click on 'bydhvs.x.CellDetails'
3. Scroll down to 'your value'

Expected behavior
With the already determined information it should be possible to add an additional folder per module.

Versions:

• Adapter version: 1.5.0

Additional context
If you @christianh17 as adapter owner agree I will create a PR with this solution in it.

I am not sure, it breaks the scripts and logic if we change the structure of the objects. And: In my opinion the right way is not to use the objects "itself" but some kind of visualisation depending on the objects.
On the other hand: You did a great job in enhancing the adapter and I can see: Other people do use the objects itself.
What about a compromise: A switch in the configuration from the adapter and one can choose between the "old" (actual) behaviour and a more structured way for the cell details.

The issue is some days older, there have been changes. Do you think a change is still neded?
