SpatialController dependency/import issues

Couple of complaints about the spatialcontroller package, in the AccessoryTrackingHelper class

line 7
using Unity.VisualScripting;

this shouldn't be here - it's not used, but causes compile errors if you don't have that package. This seems like it's just clearly a bug/mistake

line 14
using Unity.PolySpatial;

We don't use polyspatial at all - polyspatial is added as a dependency to the package just to check if you are in a specific camera mode. It's so much extra bloat just for something we don't care about or need. I believe you can use "Version Defines" to make this code optional for people who have polyspatial in their project, rather than making it a forced dependency

Also, when using the package, it seems to require a hand tracking description - even though we aren't really using hand tracking. To make things slightly more annoying, the hand tracking description box in the xr project settings is greyed out if you don't have unity.xr.hands in your project

Beginne mit der Klasse AccessoryTrackingHelper und untersuche die Abhängigkeiten des Pakets spatialcontroller sowie den Code um die Zeilen 7 und 14. Prüfe, ob das Paket ohne Unity.VisualScripting oder Unity.PolySpatial kompiliert werden kann, und untersuche anschließend die Anforderung an die Beschreibung des Hand-Trackings in den XR-Projekteinstellungen; die Arbeit ist abgeschlossen, wenn keine unnötigen Abhängigkeiten erzwungen werden und das Paket ohne eine nicht verwendete Einrichtung des Hand-Trackings funktioniert.
