Swap ISS position API priority to avoid timeout delays

Browse Source 
Open Notify API (api.open-notify.org) is frequently unreliable,
causing 5-second timeout delays on every ISS position request.
Promote wheretheiss.at as the primary API in both satellite.py
and sstv.py, demoting Open Notify to fallback.
