- Improved error handling in `python_enable_motor.py` by capturing and displaying exception details.
- Ensured proper CAN bus shutdown in `python_enable_motor.py` with a `finally` block.
- Refactored `python_send_angle.py` to accept a command-line argument for the target angle instead of looping indefinitely.
- Refactored `python_send_velocity.py` to accept a command-line argument for target speed and removed infinite loops for better usability.
- Added `send_velocity_impulses.py`, a new script to send alternating velocity impulses over the CAN bus.
