Counting slots fixed one half of the problem; this fixes the other. A slot is
now filled by a spool of the same material whose colour is close to what the
slot asks for, one spool per slot, best matches assigned first. So four PLA
slots in black, blue-grey, grey and white are not satisfied by four spools of
white — only the white slot is.
Closeness is redmean distance with a tolerance of 50, which treats genuinely
near shades as the same colour while keeping #000000 and #161616 (about 66
apart) distinct. Slot colours arrive as #RRGGBB and #RRGGBBAA — the alpha
channel is parsed off rather than making the colour unreadable.
The model page now lists every slot: its colour, which spool fills it, and the
nearest thing on the shelf when nothing does.
Two things this fixes in code I wrote an hour ago: renderDetailPrintable still
called a function the rewrite removed, so opening any model would have thrown;
and the README claimed colours weren't matched.
