MonadST instance for ParserT?

https://pursuit.purescript.org/packages/purescript-st/6.0.0/docs/Control.Monad.ST.Class#v:liftST

Then we could replace doST with liftST here

purescript-parsing/src/Parsing/String/Replace.purs

Lines 483 to 485 in c160c90

    
           -- Sequence ST operations in some other monad. What could possibly go wrong? 
        
           doST :: forall b. ST Global b -> m b 
        
           doST = pure <<< unsafePerformEffect <<< toEffect

Actually we should just use Array.reverse for all this instead of Array.ST.
