dotCooCoo 591cb579b3 Swatches: Load Swatches refuses .ase files over 100,000 colors and merges in linear time ...

ase::read accepted any number of colors in a swatch exchange file, and
swatch.load looked up each incoming name with a linear search through
the document's swatches. The time to load a file grew with the square of
its number of colors: in a test build, 50,000 colors used 2.5 s of CPU
and 100,000 used 9.6 s. No limit applied to larger files.

ase::read now returns an error for a file with more than 100,000 colors
(ase::MAX_COLORS). load_swatches looks up each name's first swatch in a
HashMap, and each color added from the file is indexed too. A file of
100,000 colors now loads in under 0.1 s. The merge follows the same
rules as before: names already in the document are kept unless replace
is set, a name repeated in the file matches its first copy, and a
locked swatch is left unchanged.
