Replace unwrap() to something else.

let iso_obj: Value = serde_json::from_str(&iso_data).unwrap();

Hi.
As I see, there are a lot of unwrap() methods all around the code. For example above. These calls will panic in case of Err results of unwrapped operations. If this behaviour isn't intended I suggest to use something like unwrap_or(), ok_or() or something else of option API.
