Added unit tests. I'm using http://www.russellcottrell.com/photo/matrixCalculator.htm to compute the conversion matrices, and https://colorjs.io/ to generate and compare expected values for tests. Color.js is written by co-authors of the CSS Color 4 specification. |

Description
Adds
THREE.DisplayP3ColorSpace
constant, and related CPU-side transforms in THREE.ColorManagement. No rendering code is affected — the only direct effect is thatcolor.getStyle( 'display-p3' )
will now apply a conversion.No gamut mapping is applied. Given a Display P3 input that is out-of-gamut for sRGB, conversion to sRGB will yield RGB values outside the range [0, 1]. That is the only lossless choice, which I think is important here, and users can use Color.js or other libraries to select an appropriate gamut mapping method if necessary.
