🚀 Function to check if request came from localhost

[GarryGaller]

Could you build into the library a simple function that guarantees that the request came from a local host?
That would be handy than writing your own bike every time, which often isn't quite right enough yet.
Let's say this option doesn't work correctly.

func GetIPs(c *fiber.Ctx) []string {
    ips := c.IPs()
    if len(ips) == 0 {
        ips = append(ips, c.IP())
    }
    return ips
}

func NextIfLocal(c *fiber.Ctx) bool {
    return GetIPs(c)[0] == "127.0.0.1"
}

This one's better:

func IsLocalHost(address string) bool {
	/*
		fmt.Println(IsLocalHost("::1"))
		fmt.Println(IsLocalHost("::1:3001"))
		fmt.Println(IsLocalHost("127.0.0.1:80"))
		fmt.Println(IsLocalHost("0.0.0.0"))
		fmt.Println(IsLocalHost("178.10.10.10"))  // false
	*/

	localHosts := []string{"localhost", "127.0.0.1", "0.0.0.0", "::1"}
	for _, h := range localHosts {
		if strings.Contains(address, h) {
			return true
		}
	}
	return false
}

func NextIfLocal(c *fiber.Ctx) bool {
	return IsLocalHost(GetIPs(c)[0])
}

Are you still working on it?
If you are busy, maybe I can take it. @muratmirgun
