12ba057b4f Check that colour slot is non-empty before checking for gray-ness
This is otherwise UB, and trips a GLIBCXX assertion (when enabled).

d86d24bdc1 Remove legacy support for generating a palette with unused colors
If you need an explicit set of colors, possibly including
unused ones, use `-c`.

92eb0a133b Allow rgbgfx -r to read an infinite amount of tiles without tilemap
Previously, indices would be wrapped after 256 even without a tilemap;
since RGBGFX can generate arbitrarily large tile data if `-N` is not used,
it should be possible to read those in.

Of course, this won't work if a tilemap is provided, but such "big blobs"
can't generate a meaningful tilemap anyway.

fcce42d3d2 Avoid sorting proto-palettes breaking mappings
The sorting was performed without updating the mappings, which broke the world.
We can instead sort the IDs as they are inserted into the packing queue,
which should also be faster than moving the actual proto-pal objects around.
