Add Generate Words button

[nmillin]

I have a 1st and 3rd grader who were recently introduced to Spellie by the 3rd grader's teacher. My 3rd grader does pretty well with the easy and medium words, but my 1st grader doesn't have a large enough vocab to play the game.

I added a "Generate Words" button that will help give word (5) suggestions. The suggestions take into consideration what correct letters have already been guessed, but doesn't go too far by removing wrong guesses (I didn't want to make it too easy and that was more effort...).

https://nmillin.github.io/spellie/ is the URL where people can play the game.

Note My code is very hacky and lots of comments that should be removed. I was under a time crunch and just wanted something to work. Let me know what you think.

Thanks!

Thanks for creating a PR. This is an interesting idea.

I'll have to think a bit more about how the UI for this would work.

We could build it into the existing hint system. I wonder if could operate like the Wordle Bot, trying to help solve your puzzle without any knowledge of what the answer is but knowing what good guesses would be based on the current game state.
