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.
