Refactor motion sequence handling: remove old test script, update setup, and implement new runner with configuration support

- Deleted obsolete `test_motion_sequence.py` file.
- Updated `setup.py` to remove references to the old test script and motion configuration file.
- Added `motion_sequence_config.json` to define home position and waypoints for the robot.
- Introduced `motion_sequence_runner.py` to execute motion sequences based on the new configuration format, supporting both joint and pose movements.
