Function code response error handling needs improvement

[KaneTW]

Not all function responses can currently be handled. For example, I have a device that outputs FC code 0x2 (RR, resource error) after two weeks of operation. Pyprofibus doesn't notice and just outputs a datagram with empty data.

Thanks for your message.

Are you able to implement such error handling? If so, please feel free to submit a pull request with your suggested implementation.

I'll submit a PR once I have an implementation.
