  - generate_config: Move filters to external library

    Clean and isolate main script logic from custom filters by moving
    all them to a external library file.
    Library has a function to load all the existing filters at once.

    New enhanced IP handling custom filters:
     - ipnet_hostaddr
     - ipnet_hostmin
     - ipnet_hostmax
     - ipnet_broadcast
     - ipnet_netmask
     - ipnet_contains_ip
     - ipnet_contains_iprange
     - ipnet_range_size

    ipnet filters work with proper IP network with prefixlen mask,
    ensuring consistent IP calculations and error handling.

    Previous IP handling filters should be deprecated.
