Phase 1 Complete: Preparation & Cleanup

Directory structure:
- Created src/sensorpajen/ for new Python package
- Created config/ for configuration templates
- Created legacy/ for old scripts
- Created systemd/ and debian/ for future phases

Package setup:
- Added pyproject.toml with modern Python packaging
- Created package __init__.py
- Defined dependencies: bluepy, paho-mqtt

Configuration:
- Created config/sensors.json.example (converted from INI)
- Created config/sensorpajen.env.example for environment variables
- All 8 Xiaomi sensors migrated to JSON format

Cleanup:
- Removed temperatur_koksfonstret.py (DHT11 functionality)
- Moved all legacy scripts to legacy/ folder:
  - LYWSD03MMC.py
  - bluetooth_utils.py
  - sendToMQTT.sh
  - sensorer.sh
  - startup.sh
  - sensorer.ini

Updated ROADMAP.md to mark Phase 1 as complete.
