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

AccessoryTrackingHelper クラスから始め、spatialcontroller パッケージの依存関係と、7 行目および 14 行目付近のコードを調査します。Unity.VisualScripting または Unity.PolySpatial なしでパッケージをコンパイルできるか確認し、その後、XR プロジェクト設定におけるハンドトラッキングの説明要件を調査します。不要な依存関係が強制されず、未使用のハンドトラッキング設定なしでパッケージが動作すれば完了です。
