Trim weather-tag vocabulary to audio-relevant precipitation only

Drops clear/cloudy/fog/windy and the wind-speed override — those
conditions sound the same on the recordings, so they don't earn a tag.
Also renames "rainshower" → "rainstorm" and rebalances the rain
mapping so 503/504/522 (extreme + heavy showers) get the storm tag.

Final vocabulary: thunderstorm, rain, rainstorm, snow, snowstorm.
Anything else falls through to the un-tagged filename.
