Enable support for 5530 and connection type "fiber"
**Describe the solution you'd like**
I am using your plugin since one week on a FritzBox 5530 with fiber connection. So far everything works as before with DSL on a 7490, so I would like to have the device be added to the supported ones. In addition I would suggest to add the connection type "fiber" to the already existing ones "dsl" and "cable".

**Additional context**
If I can support you with any log files/debug files that would show if everything works well on the 5530 please let me know.
