Add wafer layouts and RBF heatmap functionality

- Introduced new YAML layout files for wafers B, C, D, F, X, Z, and their reversed versions.
- Implemented RBF heatmap interpolation using CuPy and NumPy for GPU acceleration.
- Created a backend module to load wafer layouts from YAML files, mirroring the existing schema.
- Developed a QQuickPaintedItem for rendering wafer maps, including sensor markers, heatmaps, and labels.
- Enhanced the drawing capabilities with concentric rings, crosshair axes, and orientation markers.
