[Haskell] ANNOUNCE: graphviz-2999.13.0.0

[Ivan Lazar Miljenovic]

I should have pointed out that for most people, there should be
minimal to no API change with this release; the only change I needed
to make in my own code was that a type-class I had defined in
Graphalyze was removed as it provided the impetus for the ToGraphID
class mentioned below.

> * Dropped support for base-3.
>
> * The `Data.GraphViz.State` module is no longer exposed, as there's no
