[Source Defect]: zaw_sr_de ignores addition (house number suffix) Argument

[Todt40]

Source Name

zaw_sr_de

What's happening?

The addition argument (house number suffix, e.g. "A") is not being used when fetching data. When set, the source returns the schedule for the plain house number instead of number+suffix.
I used the UI to configure the integration, but with values matching the source configuration field.

Error Logs

No errors in the Home Assistant logs — the source fetches successfully without exceptions, it just silently ignores the `addition` parameter and returns data for the base house number instead.

Source Configuration

waste_collection_schedule:
  sources:
    - name: zaw_sr_de
      args:
        city: Schwarzach
        street: Harpfen
        hnr: "4"
        addition: A
