✅ Pull Request: Stable 1.0.0 Release — Modernized & Backward Compatible

Summary

This PR upgrades the Global Macro Database Python package from 0.3.1 to 1.0.0, marking it as a stable, production-ready release.

Key improvements:

• ✅ Rename gmd() to get_data(); more pythonic, results in clearer calls such as gmd.get_data()
• ✅ Refactor list functions from old gmd() function to standalone functions.
• ✅ Modify list_countries and list_variables to return DFs (default) or dict.
• ✅ Add ability to use country name instead of ISO code in get_data().
• ✅ Remove print statements in favour of logging and custom error handling for easier debugging.
• ✅ Migrated to pyproject.toml (PEP 621) with setuptools.build_meta.
• ✅ Cleaned up legacy setup.py usage — fully PEP 517 compatible.
• ✅ Confirmed backward compatibility for Python 3.8+ (pip 19+, setuptools 42+).
• ✅ Improved tox matrix for cross-version testing — Python 3.8 onwards
• ✅ Robust test coverage for all main functions.
• ✅ Removed local .egg-info and ensured .gitignore is clean.
