Exception thrown by stringifyAny

[mununki]

Js.Json.stringifyAny has a chance to throw an exception, TypeError. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify#exceptions

Js.Json.stringifyAny: 'a => option<string>

I think it is better to rename it to stringifyAnyExn or to wrap it with try-catch.
