Feature Request: store radar station id

[MatthewFlamm]

~~When retrieving point data, the radar station is returned. It should be possible to fetch the radar loop.!~~

• [ ] ~~This is already done in MatthewFlamm/nws_radar, but it is not async. Can this be reworked inside here? The lite radar station interface is much simpler, so start there.~~

But, this would be done outside the api.weather.gov API. So, maybe the retrieval of the image/loop doesn't belong here, but we can store the radar station ID so that nws_radar can be used to retrieve the image.
