refactor: (arm) consolidate velocity control VicCAN into single function

- Add @warnings.deprecated decorators to callbacks that use old topics
- Rename "*new*" topics
- Print debug on malformed message receival
- Un-invert Axes 2 & 3 in the URDF
- Don't silently check mcu_name twice
- Remove threading.Thread (not one of Riley's comments)
- Add a real signal handler (ditto)
- Move stamped stop messages to helper functions
