Register the XYZ-D65 color space

[dontwanttothink]

Resolves #8806

I'm not sure whether this is the right approach. I didn't want to expose an additional color mode, so the color space is registered with color.js directly. The color space XYZ-D65 needs to be registered somehow, I think, in order for lerp to work between sRGB, Lab and Oklab colors.

Unfortunately, any time I tried to test this change, p5.js crashed with a message complaining about a totally different color space, HSB, being registered twice. Curiously, this happened even when I tried testing the base branch (i.e., without the change).

As a result, I'm submitting this as a draft in case it is of any use.

Changes:

• Fixed: Attempting to interpolate between colors defined in different color spaces could throw an exception in some cases.
