Multicolor Paint only showing 16 colors #12247

Description of the bug

When painting on colors for multi-color printing, only the first 16 colors are presented as options, despite having 20 colors defined. I tried this with 19 and 20 colors defined, both of which cut off at 16.

I assume this is just a max limit. It should be 32 or 64, to allow for a decent size pallet that I can always use rather than customizing the virtual tools list for each print job.

1) Configure PrusaSlicer for > 16 colors. 2) In Editor view, select the object. 3) Click the drop list for either First or Second color. You will only see the first 16 colors there.
