Function convertBeamAdapterAction not used

I just noticed the following warning:

```bash
BeamAdapter/src/BeamAdapter/utils/BeamActions.h:58:30: warning: unused function 'convertBeamAdapterAction' [-Wunused-function]
    static BeamAdapterAction convertBeamAdapterAction(const std::string& sAction)
                             ^
```

Is there a reason why it is not used?
