* require Geo::Distance, not Geo::Distance::XS

  The problem with "require Geo::Distance::XS" is: the import()
  function is never called, but this function actually does the
  overwrite of the distance() method. So the "used once" warning was a
  real problem, and shouldn't be ceased at all.

  It's better to just say "require Geo::Distance" --- if the ::XS is
  available, then it's anyway automatically loaded, and it's done
  right.
