Performance fixes

Release September 2025 [1.11.1]

🚀 Overhaul of internal bootlnecks that hampered performance on some systems and caused GUI freezing / high CPU loads.

Bugfixes 🐛

• fixed excessive communication between threads causing high CPU load on some systems.
• moved serial_worker into core thread to avoid conflicts of relative motion operations with GUI thread.
• added CPU core identifiers for different operations in debug mode or logging, to pinpoint performance issues.
• fixed autofocus (AF) function in the GUI.
• returned 'camera_display_live_subsampling': 2, , 'camera_display_acquisition_subsampling': 2, and 'camera_display_temporal_subsampling': 2, into the config file, to reduce camera display load on older computers.
• fixed light-sheet markers and box ROI markers in the Camera window, which were not displayed correctly after zoom change.
