Citeproc changes:

T.P.Citeproc exports `getCiteprocLang` and `getStyle` [API change].

T.P.Citeproc.Locator now exports `toLocatorMap`, `LocatorInfo`,
and `LocatorMap`.  The type of `parseLocator` has changed, so
it now takes a `LocatorMap` rather than a `Locale` as parameter,
and returns a `LocatorInfo` instead of a tuple.
