Purescript pipes

Port of the haskell pipes library by Gabriel Gonzalez to purescript: https://hackage.haskell.org/package/pipes

Thanks to

@scott-christopher for porting ListT and writing the MonadError, MonadWriter, MonadPlus and Alternative instances for Proxy!

For an in-depth overview of pipes follow the tutorial that comes with the Haskell pipes library. The concepts apply one to one to purescript-pipes.

Also have a look at the examples that come with purescript-pipes. You can run them using npm run example.
