Core

• Minimal supported python version is 3.9
• Removed dependency on scikit-image
• Updated Random number generator from np.random.state to np.random.generator. Second is 50% faster => speedups in all transforms that heavily use random generator
• Where possible moved from cv2.LUT to stringzilla lut
• Added parameter mask_interpolation to Compose that overrides mask interpolation value in all transforms in that Compose, now can use more accurate cv2.INTER_NEAREST_EXACT for semantic segmentation and can work with depth and heatmap estimation using cubic, area, linear, etc

BugFixes

• Bugfix in bounding box filtering
• Bugfix in OpticalDistortion
