tryCatchIntoResultAsync

This function converts the returend value from producer into Ok(T). If producer throw a something, this returns it with wrapping Err(unknown).

NOTE:

1. An user should narrow the scope of producer to make it predictable that is in Err(E).
2. Basically, we don't recomment to use this to create a Result<T, E>. Generally, you should define an Err(E) by depending on an use case context Use this operator just to make a bridge to existing codebase that you cannot inspect deeply to details.
