Create a function that counts the number of times a particular letter shows up in the word search. Examples letterCounter([ ["D", "E", "Y", "H", "A", "D"], ["C", "B", "Z", "Y", "J", "K"], ["D", "B", "C", "A", "M", "N"], ["F", "G", "G", "R", "S", "R"], ["V", "X", "H", "A", "S", "S"] ], "D") ➞ 3 // "D" shows up 3 times: twice in the first row, once i
