A function to convert text to typoglycemic format with a Leet-speak variant. The function takes a string as input and returns a new string where the first and last letters of each word are unchanged, but the middle letters are shuffled randomly. Additionally, certain letters are replaced with their Leet-speak equivalents (e.g., 'a' becomes '4', 'e' becomes '3', etc.). This creates a fun and visually interesting way to obfuscate text while still keeping it somewhat readable.
