Handle invalid result from quantize palette call #9

Sometimes, the palette from the CMap of quantize can return false, leading to an uncaught error. This helps catching it smoothly by returning an empty array.

After further investigations, it often happens when providing an invalid value of RGB color values. I can create another PR / update this one to prevent this by throwing an error or resetting the value to a valid one, as you prefer @tj.
