feat(tools): add vibration_check.py for VIBE log analysis

[aryanputta]

Closes #1185

Summary

Adds tools/vibration_check.py, a standalone command-line script that reads ArduPilot VIBE dataflash messages from .bin or .tlog log files and reports per-axis vibration statistics with pass/warn/fail thresholds.

The script mirrors the style of the other analysis tools already in tools/ (e.g. magfit.py, mavfft.py) and requires only pymavlink as a dependency.

What it does

• Parses VIBE messages (VibeX, VibeY, VibeZ, Clip0/1/2) using mavutil.mavlink_connection
• Computes per-axis min, mean, and max vibration in m/s^2
• Compares peak values against configurable warn (default 30 m/s^2) and fail (default 60 m/s^2) thresholds from ArduPilot documentation
• Reports cumulative IMU clipping event counts with separate warn/fail thresholds
• Exits with non-zero status on warn (1) or fail (2) so it can be used in CI or preflight automation
• Optionally writes per-sample data to a CSV file with --csv

Usage

python vibration_check.py flight.bin
python vibration_check.py flight.bin --warn 30 --fail 60
python vibration_check.py flight.bin --csv --output report.csv
