* Implement Fan control for TG WVP2. Calculate approximate fan speed. Catch two exceptions. Remove leftover close in ReadConfig. * Support for multi device detection * Add more data to report * Add group for power monitors and remove from GenericGpu. * Move files. Add option for Power Monitor in Computer + UI.
