Build broken on Windows

[isovector]

As part of Cornelis' new CI infrastructure (thanks @malob!), we're seeing the following build failure on windows:

nvim-hs                          > [14 of 28] Compiling Neovim.RPC.Common
nvim-hs                          > 
nvim-hs                          > library\Neovim\RPC\Common.hs:91:18: error:
nvim-hs                          >     * Variable not in scope: getSocketUnix :: FilePath -> IO Socket
nvim-hs                          >     * Perhaps you meant `getSocketUDP' (imported from Data.Streaming.Network)
nvim-hs                          >    |
nvim-hs                          > 91 |         liftIO $ getSocketUnix f >>= flip socketToHandle ReadWriteMode
nvim-hs                          >    |

I'll have to figure out which kinds of connections are supported for Neovim on Windows.

In theory, Windows 10 and onwards should support Unix Sockets and so Neovim might support them as well. However, streaming-commons has an ifdef to not include that functionality on windows.

I've tried a quick fix and noticed that the code generation from nvim --api-info doesn't work on windows. So, this has become even more complicated to fix. :-(

It should build and work on Windows with a version equal to or newer than https://hackage.haskell.org/package/nvim-hs-2.3.0.0

Amazing, thanks!
