Simple Weather

Added new configurable setting allowing weather to persist through sleeping. Thunderstorms will still settle to gentler weather. In order for this to work on server playthroughs, it must be added to the server side.

New volumetric libary dependency allowing mods to specify regions in which weather can either be "deterred" (prevented) or added as a weather region. While there are plans to make a maven central based api package with sources, for now using the curse forge maven and using the `api` package is likely more reasonable at the moment. You will need to add Volumetrics to your dev environment when using the api so you have access to the `Cuboid` class, but you yourself don't need to depend on `Volumetrics` if you don't want to in production (it is will be needed for the dev environment). Setting up a soft dependency on Simple Weather is more advised than full on requiring it.
