Converts the given JSON-string input to its corresponding object.
Parsed JSON values are of the types num, String, bool, Null, Lists of parsed JSON values or Maps from String to parsed JSON values.
If this was initialized with a reviver, then the parsing operation
invokes the reviver on every object or list property that has been parsed.
The arguments are the property name (String) or list index (int), and
the value is the parsed value. The return value of the reviver is used as
the value of that property instead the parsed value.
Throws FormatException if the input is not valid JSON text.
