Haskell IDE Engine Options Support

Since support for the [Haskell IDE Engine](https://github.com/haskell/haskell-ide-engine#configuration) (hie) was initially added, hie appears to have gone through a few changes. One of these is that hie-wrapper, the main executable, requires one to pass the `--lsp` flag for language server protocol output. Otherwise, it prints to stdout. Since there does not appear to be the ability to add options for hie, ALE's support for hie is essentially broken for the current version. In addition, adding support for specifying hie's options will likely protect ALE's hie support from similar future changes.
