We define a 'cpack' here as a (3 byte color code) number that can be expressed like 0xFFAA66 or so. For that reason it is sensitive for endianness... with this function it works correctly.

Compute luminance using Rec.709 primaries, for sRGB and linear Rec.709.

Only use for colors known to be in sRGB space, like user interface and themes. Scene colors should use IMB_colormanagement_get_luminance instead.
