Add sharing feature and identifier for word

[JonathanWThom]

It would be nice to print out the shareable colored squares at the end of a won game.

However, since the words are selected at random, it's useless to share your result since no one else can be assured to be playing the same word. To get around this, each word should have some sort of identifier (that doesn't give away what it is), that can be passed as an argument by your friends, so they can play the same word.

Instead of "Wordle 202 4/6" and then the squares, it would be something like "Wordle Gem 4/6".
