CAM16 Jab is non-standard, keep only the standard forms of the spaces.
LCh spaces can't have negative chroma, so we clamped them during assignment. Additionally, Jzazbz algorithm clamps negative lightness during conversion, and CAM16 related spaces break down if negative lightness is used. In such spaces, we clamped lightness during assignment as well. Moving forward, we will not do this, but let such clamping occur only during conversion.

I'm actually going to split up this work as I'm not sure I want everything in this.
