Parses a string or data object and converts it in data structure.

@param [String, NSData] str_data the string or data to serialize. @raise [ParserError] If the parsing of the passed string/data isn't valid. @return [Hash, Array, NilClass] the converted data structure, nil if the incoming string isn't valid.

TODO: support options like the C Ruby module does
