Command line tool to convert ULID to and from UUID/GUID

The ULID (Universally Unique Lexicographically Sortable Identifier) is a new format for unique identify. The definition can be found under ULID spec

The older and lesser readable UUID/GUID ('Universally Unique Identifier'/'Globally Unique Identifier') is a more used unique identifer in multiple implementation like Databases and SDK's.

Both Unique identifier are convertable from one to the other.

The idea behind this tools is to give a simple console command to convert between UUID and ULID in a simple way.
