printf formatting for anonymous records

[OnurGumus]

let person  = {| FirstName = "John"; LastName = "Doe" |}

printf "%A" person

In fable this compiles to

import { printf, toConsole } from "fable-library-js/String.js";

export const person = {
    FirstName: "John",
    LastName: "Doe",
};

toConsole(printf("%A"))(person);

and prints
[object Object]

In .NET it would print something like
{ FirstName = "John"; LastName = "Doe" }

I am not entirely sure if this is solvable as the intention looks like converting anonymous records to plain objects and it helps with JS interop.

The problem seems to be printing was defaulting to Object.toString. I PRed a fix for that, still not the same behavior as .NET but I guess it's more informative for debugging.
