Overview

So my suggestion is to add 12 new block/item tags so you can make a crop fertile in just 1/3 of the season.
You can keep the existing tags, which will just be a short-way of saying that it's fertile in the whole season.
(Keeping them will not break compatibility with existing mods, just allow other mods/modpacks to fine-tune crops via datapacks.
Example: Crop is added to late summer, early autumn and mid autumn crop tag -> You can grow it just this 3 sub-seasons.

Why would this feature be useful?

It makes crop fertility 300% more customizable, making this mod atleast 300% more awesome.
