    [color] Rewrite colr access
    
    COLR table has one function: return layers for a glyph, and we expose exactly
    that, so should just wire it through.  Also use sub_array() for verifiable
    safety.
    
    Also, BaseGlyphRecord's null object is enough.  We don't need to special-case
    the not-found.

    We never return parallel arrays from functions.  That's inconvenient
    and hard to bind.
