Compatibility with Seasonal Horizons

[DarkShadow44]

My new season mod Seasonal Horizons changes the temperature in winter. This leads to snow where vanilla would render rain.

This PR adds compatibility by using the season API to check biome temperature.

Once I'm back from vacation later this week I'll take a look in-game. Is there a reason someone might want to disable the compat? If so I'll add it to the config.
Code wise, is this something OptionalInterface could be used for? I vaguely remember it existing for things like this but I've never used it

I don't see why someone would want to disable compat - that would make rain/snow render wrong and cause other issues like this. If they want seasons, all mods should treat winter like winter.

The optional annotations are a thing, but I don't think they are useful here. They're useful if you implement a mod's interface and want to strip that out if the mod is not loaded.
