Allow dependency injection for “is-ip” in “get-client-ip-address”

[GuptaSiddhant]

Currently “get-client-ip-address” util accepts only one parameter and uses “is-ip” package to check if the header value is a IP address or not.

But on NodeJS, as pointed out by README of “is-ip” package, there is built in “net.isIP”.

If the api of the util is updated to accept a second predicate parameter which accepts a function to check the if the input is IP.

type PredicateFn = (input: string) => boolean;

User can pass the “isIP” function from “is-ip” package or pass a custom function based on NodeJs net lib.

import net from “node:net”;
const isIP = (input:string) => net.isIP(input) !== 0;

This can reduce one extra dependency for apps that only depend on single type server runtime, since other runtimes may provide their native ip checking function.
