Self-contained Wordle game

[#1]

Following @ChrisHemedinger's posts here and here, here is my contribution.

Just one macro that can be saved in your macro library.

Run %wordle(help) to see this help screen: 

==================================================================
               WORDLE Game                                
==================================================================
                                                          
  These commands are available:                     /\"_"/\    
                                                   ( ='.'= )   
   %wordle(HELP) to display the help screen        (") "" (")  
   %wordle(NEW) to start a new game                  |"  "|    
   %wordle(CONTRAST) for Hi-Vis colours             /"/  \"\   
   %wordle(guess) to propose a solution            (")"||"(")  
                                                       ((      
   These words are case-insensitive.                    ))     
   The words HELP, NEW, CONTRAST are reserved.         ((      
   If you propose a word when no game is active,          
     this word becomes the word to guess (useful for debugging). 
                                                          
==================================================================

This game shows your attempts and updates the used letters on a QWERTY keyboard.

Not much time spent on QA, so use at your own risk.
