Evan Borden 2600524274 Add stylish-haskell as a fixer (#1837)
* Add stylish-haskell as a fixer

`stylish-haskell` is a common formatting tool for the haskell toolchain.
It is not as advanced as `brittany` or `hindent`, but it is commonly
used for formatting of imports and data declarations. This adds it as a
fixer in ALE.
