Add CIE's 1964 UVW color space support

[castarco]

It would be interesting to add support to the CIE's 1964 UVW color space (Not to be confused with the CIE's 1960 color space, nor the CIE's 1976 color space).

I propose to name the class CIE1964 instead of CIEUVW because it's not a widely used color space and I think it's probable that some programmers use the wrong classes if we name it with its coordinate symbols.
