Title: New hsl 2 rgb conversion

This branch switches out the HSL -> RGB conversion algorithm and updates the test fixtures. The old algorithm would fail with very high hue & saturation with low lightness [350, 90, 0.1] by generate negative blue values.

Please note that this does change the output of the tranformation. From what I've seen the difference can be 5/255 and it is visible. See `test/tinted/sydney_270_50_1_0.5.png` in the diff.
