sl-controls 2919e629e9 feat: Add velocity smoothing filter with Butterworth low-pass filtering
Implements saltybot_velocity_smoother package:
- Subscribes to /odom, applies digital Butterworth low-pass filter
- Filters linear (x,y,z) and angular (x,y,z) velocity components independently
- Publishes smoothed odometry on /odom_smooth
- Reduces encoder jitter and improves state estimation stability
- Configurable filter order (1-4), cutoff frequency (Hz), publish rate
- Can be enabled/disabled via enable_smoothing parameter
- Comprehensive test suite: 18+ tests covering filter behavior, edge cases, scenarios
