Refmterr Introduction

Refmterr is an error formatter for Reason and OCaml builds. It takes raw error output from both the Reason and OCaml compilers and converts it to pretty output like so:

## Before ##

File "type_AppliedTooMany_3.ml", line 11, characters 5-30:
Error: The function applied to this argument has type
         customLogOutputProcessors:(string -> string) list ->
         customErrorParsers:(string * string list) list -> unit
This argument cannot be applied with label ~raiseExceptionDuringParse

 ## After ##

 ERROR  type_AppliedTooMany_3.ml:11 5-30

 8 ┆ let _ =
 9 ┆   parseFromStdin
10 ┆     ~refmttypePath
11 ┆     ~raiseExceptionDuringParse=true
12 ┆     ~customLogOutputProcessors=[]
13 ┆     ~customErrorParsers:[]

The function has type (
  ~customLogOutputProcessors: list(string => string),
  ~customErrorParsers: list((string, list(string)))
) =>
unit

This function doesn't accept an argument named ~raiseExceptionDuringParse.
