    Switch the package id types to use FastString (rather than String)
    
    The conversions should now be correct w.r.t Unicode.
    
    Also move a couple instances to avoid orphan instances.
    
    Strictly speaking there's no need for these types to use FastString as
    they do not need the unique feature. They could just use some other
    compact string type, but ghc's internal utils don't have much support
    for such a type, so we just use FastString.
