Update: The f_network_is_ip_address() to use f_string_range_double_t (soon to be f_range_double_t).

This allows for getting both the address and port range positions.
The POSIX/libc functions do not support the bracket notation in an IPV6 address.
The string detected by this must then have the brackets filtered out.
This new structure allows for saving the range.

I did a quick run-through write-up of the logic for these changes but I have not spent any time reviewing or testing the logic.
Hopefully there are not logic bugs or mistakes.
