* Add verbose option
* More sensible response when a plugin legitimately refuses to initialise
* Actually throw an exception when failing to load a plugin, instead of just
  saying that we do so in the comment but actually crashing instead

    This program loads a Vamp plugin and tests its susceptibility to a
    number of common pitfalls, including handling of extremes of input
    data.  If you can think of any additional useful tests that are
    easily added, please send them to me.
