Add MeasuredDate column to all CSV files

Browse source 
CHANGES:
- Added MeasuredDate as first column in regional.csv
- Added MeasuredDate as first column in muscle_balance.csv
- Updated README to document new column structure

BENEFITS:
✅ Track regional changes over time (e.g., Arms fat % across scans)
✅ Easy time-series analysis with pandas/Excel
✅ Filter by date range for progress tracking
✅ Consistent date column across all 3 CSV files
✅ Enables queries like: 'Show me trunk fat % over last 6 months'

EXAMPLE USAGE:
  import pandas as pd
  regional = pd.read_csv('regional.csv')
  arms = regional[regional['Region'] == 'Arms']
  # Now you can track Arms progress over time!

Each scan now adds:
- 1 row to overall.csv
- 6 rows to regional.csv (one per region)
- 6 rows to muscle_balance.csv (one per limb comparison)
