Description
Add the remaining blend modes from https://www.w3.org/TR/compositing-1: hue, saturation, color, luminosity. Also try to implement them for polar color spaces, as suggested in #178, to be able to close it. They should be implemented as their own trait, since they are quite different form other blend modes. The color types must have some counterpart to the auxiliary functions that they consist of.
Motivation
These blend modes are also useful and should not be left out. The trait rework in #273 makes it easier to implement them than before, so it's time for another attempt. It would complete the set of blend modes.
