Support FritzBox fiber models
**Is your feature request related to a problem? Please describe.**
Currently I'm not able to use a Fritz!Box 5490 as master - it looks like that a new type of device **"fiber"** (beside dsl, cable, repeater) needs to be introduced

When running in debug mode the log shows
[TR064 Debug] FritzBox5490 api request 10: Ok (authenticated)
[TR064 Debug] FritzBox5490 api request 10: get /upnp/control/wanipconnection1

**Describe the solution you'd like**
new type "fiber" to be supported

**Describe alternatives you've considered**
Tried with "repeater" as type but this won't work for the master
Skipping the looping part for fiber models to get information on WAN connection would be a workaround that would it do for me
