Given a number, say prod (for product), we search two Fibonacci numbers F(n) and F(n+1) verifying F(n) * F(n+1) = prod.

// Not used for this, but here's some code to test if a number is in the Fibonacci sequence.
// const isPerfectSquare = num => {
// const sq = Math.sqrt(num);
// return sq * sq === num;
// }
// const isFib = num => {
// return isPerfectSquare(5 * num * num + 4) || isPerfectSquare(5 * num * num - 4);
