[Issue] using mapcidr as a lib in readme points to a wrong function name

[dogasantos]

Hi guys,
Found that your lib offers a mapcidr.IPAddresses function, but your Readme doc has a mapcidr.Ips reference:

// List all ips in the CIDR
	ips, _ := mapcidr.Ips("192.168.1.0/24")
	for _, ip := range ips {
		fmt.Println(ip)
	}

it should be just replaced by

ips, _ := mapcidr.IPAddresses("192.168.1.0/24")

Ty!

Thank you for pointing it out @dogasantos, the readme is aligned with the last stable release we created, we made a couple of changes after that and we planned to update them in the next release.
