- Implemented Euler to rotation matrix conversion for IMU data.
- Added function to compute linear velocity from accelerometer data with gravity compensation.
- Enhanced CSV and PNG saving functionality to automatically create directories.
- Updated statistics printing to include linear acceleration and velocity metrics.
- Expanded plotting functionality to visualize linear acceleration and velocity alongside existing data.
- Added new PNG files for IMU quality visualization.
- Updated `main.py` to include a flag for real GPIO output control.
- Added a new function in `visualise.py` to generate unique file paths for CSV and plot outputs by appending timestamps if the file already exists.
- Modified CSV and plot saving logic to utilize the new unique path function, ensuring no overwriting of existing files.
- Introduced a new image file `imu_quality_20260701_131902.png` and updated the existing `imu_quality.png`.
