4.1.0

• NEW: The powerless parameter is deprecated in average() as it is required to be always on for proper polar
  space averaging.
• FIX: Polar space averaging was not setting hues to undefined when colors are evenly distributed. This is
  required as circular means cannot be found in these cases.
• FIX: When averaging within a polar space, if the result hue is determined to be undefined at the end of
  averaging, the color will be treated as if achromatic, setting saturation/chroma as necessary. This is needed to
  prevent serialization of achromatic colors to a non-achromatic color when undefined values are resolved.
• FIX: Fully transparent colors should only contribute alpha in color averaging, regardless of premultiply
  setting. This prevents fully transparent color channels, which provide no meaningful data, from distorting averages.
• FIX: When averaging in a polar space, if a color is considered achromatic but does not have an undefined hue,
  the hue will be treated as undefined. Essentially the powerless parameter is now always True. This ensures that
  achromatic colors properly contribute to the average without distorting the hue.
