Adding a function called info which allows you to retrieve information about a given IP address or a list of IP addresses. When you pass in an IP address as a string to the ip parameter and an optional list of IP addresses as strings to the proxy_list parameter, the function will return the response as a dictionary or a list of dictionaries, depending on whether you provided a single IP address or a list of IP addresses. If there is a connection error or the IP address is invalid, an error message will be returned.
