OK, I've looked more closely at all uses of Data.FiniteMap in HaXml, and
they are far from critical, so have reverted them to using simpler
lookup structures.

As far as I can tell, none of my other software now depends on FiniteMap
either, so I withdraw the threat to resuscitate it.  (Sorry Duncan!)
