09. Define a function pig_latin() which plays the Pig Latin language game with function inputs.

• For words that begin with consonant sounds, all letters before the initial vowel are placed at the end of the word sequence. Then, "ay" is added. e.g. "pig" -> "igpay". When words begin with consonant clusters (multiple consonants that form one sound), the whole sound is added to the end. e.g. "smile" -> "ilesmay"
• For words that begin with vowel sounds, the vowel is left alone, and "yay" is added to the end. e.g. "eat" -> "eatyay"
