* Added check for mandatory "arg" of sensors
* Make pylint happy
* Moved to vol validator function for "arg" checks
* Make pylint happy once again
* Adjustments from code review
* Improvements for systemmonitor
* Use MDI CPU icon (bit architecture determined at runtime)
* Consistent usages of "percent" (ensured backwards compatibility by explicity setting the entity_id)
* Default value "/" (root) for disk_* sensors to prevent runtime issues if not specified in configuration
* Added CPU temperature sensor to systemmonitor
* Code streamlining of CPU temperature retrieval
* Corrected sensor state handling and added "available" logic
* Corrected ENTITY_ID to include argument
* Optimized "available" handling & CPU temperature detection
* Corrected tuple for CPU temperature determination
* - Do not create CPU temperature entity if no sensor data can be read
- Re-use temperature sensor labels from "glances" integration
* Array fix
* Corrected sensor array access
* Handle empty temperature sensor labels (same logic as used by "glances")
* PR comments: Setting unique_ID and f-strings
* Removed unused constants
* Revert entity rename (wait until next release)
