extend functionality to include externally provided UUID's #3
Description
Great idea to make a "human memorable" UID scheme!
Currently it appears you can generate random emoji and leet sequences of various lengths strictly as a "one shot".
It would be useful to allow passed in UID's to be returned as encoded sequences also.
Currently it looks like the various generate() methods could be Python class methods rather than instance methods.
Creating Docker-style container names might also be useful.
