Ship a Vivid section of presets

Five looks for "more colourful than the default": Vivid, Vivid strong,
Vivid landscape, Vivid warm and Vivid portrait. They lean on vibrance,
which lifts muted colours most and holds skin back, and use saturation
sparingly on top; landscape and portrait work the colour mixer's bands
so foliage and sky get richer while skin does not. A sixth, Stronger
camera look, pushes the camera profile's look table to 175 %, about the
step from Adobe Standard to Adobe Vivid, and only moves vibrance where
a photograph has no profile.

All change only what they name, so they keep a corrected exposure or
white balance, and the shipped-preset tests bound every key and value.
