Mutually recursive function syntax

[samueleaton]

Doesn't support the mutually recursive function syntax as described here: https://docs.microsoft.com/en-us/dotnet/fsharp/language-reference/functions/recursive-functions-the-rec-keyword

// Mutually recursive functions:
let rec function1-nameparameter-list =
    function1-body

and function2-nameparameter-list =
    function2-body
...

Example:

let rec Even x = 
    if x = 0 then true 
    else Odd (x-1) 
and Odd x = 
    if x = 0 then false 
    else Even (x-1)

Screenshots:

Odd is not recognized as a function:

This simple addition below fixes it. I copied the .sublime-syntax file locally and it worked. I saw that the official Sublime OCaml package just has let|and in the syntax def so I copied it.

    # "and" added between "|let|" and "|member val|"

I would make a PR but it looks like you generate this from from the ionide grammar.
