New PR from - 1.2.0

• Modularized and documented functions
  • maxmind_license_download, iso_map_creation, and lanonly_map_creation now include docstrings with description, globals, locals, returns, and actions.
• More robust GeoIP management
  • Automatic download of GeoLite2-Country from MaxMind if MAXMIND_LICENSE_KEY is provided.
  • Generation of GeoLite2-Country.map compatible with HAProxy and supporting both IPv4/IPv6.
  • Global variables GEOIP_STATUS and GEOIP_REFRESHED managed consistently.
• Local access maps (lanonly.map)
  • Automatically generated from HAPROXY_ALLOWED_IPV4_PREFIX.
  • Whitespace sanitized and prefixes normalized to /24.
  • Fully compatible with HAProxy.
• Ensured directory structure
  • Dynamic creation of necessary directories (modules.files, conf.d) before starting HAProxy.
• Configuration flexibility
  • Supports multiple additional .cfg files in conf.d.
  • HAProxy starts with base and additional configuration files.
• Improved readability and maintainability
  • Refactored in bash with clear comments and docstrings.
  • Temporary files (/tmp/GeoLite2-Country) cleaned up after map generation.
• Compatibility and safety
  • Maps generated without parsing errors for HAProxy.
  • Safe initialization flow using set -e.
