Overview

Part 1 of this:

Allow changing the overall length of individual seasons
For example, raising/lowering the number of days a season will last, being able to control each subseason individually would be great but each season overall would be a good start.

Part 2 of this:

Allow enabling/disabling certain seasons, if at all possible even letting a single season be possible (if someone would want that for whatever reason)

Why would this feature be useful?

Being able to change the lengths of each season would be great for servers or modpacks that want, for example, winter to be longer or shorter, longer spings and falls, and so on.

The ability to enable and disable seasons is something I realized was missing sorely while trying to make a modpack based upon the idea. My specific example was combining this and the last part to have a long fall and winter, a short spring, and no summer.

As someone that uses the Minecolonies mod, I am in agreeance with being able to change the length of seasons. When Winter comes around the builders in that mod can't build because winter is so long so they are stuck shoveling snow. To add, it's difficult to get enough food for the Winter to supply that mod, because the warm seasons aren't long enough for the colony to supply itself and put back for the winter. Being able to adjust the Day and/or season lengths would be super beneficial. Also maybe in the future we could get an adjustment to the amount of snow that stacks on surfaces?

This would be a nice feature to have.
