spriteedit: Fix crash (array OOB) when pressing ctrl+c while editing hero sprites

(This affected the sprite editor, not spriteset browser)

The copy buffers were exactly the right size to hold one hero spriteset,
but it turns out the placer() array was 1 longer than necessary, causing
an out of bounds access! But the arbitrary sprite editor can edit much
larger sprites, so I resized the copy buffers to accomodate that instead
