Improved Weather Command (IWC)

Improved Weather Command reorganizes the vanilla /weather command and adds a way to read the current weather.

Setting weather now goes under a set subcommand:

/weather set (clear|rain|thunder) [duration]

It behaves the same as before, so /weather set rain 60 does what /weather rain 60 used to. The bare forms like /weather clear are removed.

There's also a new read command:

/weather get

It replies with whether it's currently clear, raining, or thundering.

Works on Fabric and NeoForge for Minecraft 1.21 through 1.21.11.
