feature: get current weather for a OWM weather station

[domcross]

I am running my own weather station that reports current condition every 5 minutes to OpenWeathermap (requires a free API-key to create a Station-ID). I would like to ask Mycroft for the local weather and get the conditions of my weather station instead of the interpolated conditions for my region/city.

New intent for localweather: "Hey Mycroft, what is the local weather?"

Retrieve the current condition via OWM Station-API. API-Key and Station-ID is configured in settings (home.mycroft.ai)

Result: the latest measurement for Station-ID that is returned by OWM Station-API.
