refactoring project

[shamirShahzad]

Moved many files from lib to lib/iputils to remove import cycles could not use lib/ip as in the code ip.* was clashing with variables so used ipUtils instead many other files such as bogon, cidr, utils_input, init, regex, string_slice, asn_str, u128 and errors file needed to be moved as well otherwise import cycle was being created at ipinfo/cli/lib the go install ./ipinfo is not working as there is a clash with github.com/ipinfo/mmdbctl/lib/cmd_read.go where there is use of an ip_list file which has been moved

Can we rename to iputil without the caps? Would match stuff like ioutil that is an official Go package, for example.

[shamirShahzad]

sure i will add that and create a pull request on mmdbctl which should be just one file so that i can install the ipinfo with go install ./ipinfo to test whether everthing is working can you confirm that one @UmanShahzad

[UmanShahzad]

Looks fairly clean, just fix the naming to be iputil (lowercased and without suffix s), and review comments above, and Ill do one test spin
