=> StaticArray[0.9998643703868711, 6.849859221502719e-14, 8.791283550555612e-06]
HSLuv::hex_to_hsluv(hex) -> list of floats as defined above
HSLuv.hex_to_hsluv("#ff0000")
=> StaticArray[12.177050630061776, 100.0000000000022, 53.23711559542933]
HSLuv::rgb_to_hsluv(rgb) -> list of floats as defined above
HSLuv.rgb_to_hsluv(0.99, 6.84e-14, 8.79e-16)
