Savanna farms - no more flooding

Description

Name mostly says it all.

I hate when water from mini-farms in savanna villages floods nearby area so this datapack gives you changed structures.

It removes most of the flooding. Only "small farm" structure is left unchanged because, in my testing, it is responsible for less than 5% of issues. I thought about making a flower garden or something but left it unchanged for now. If you guys have problems with "small farm", i'll change that one too.

Scope

This datapack is about as small a fix as I could manage. Houses are intact, roads are still an eyesore. I just took care of flooding.

Compatibility

Should be compatible with datapacks that change houses because I changed only one "house", one called large_farm_2, which is a farm. And will be compatible with anything what adds structures.

Not compatible with anything that changes roads (streets), because that is what I changed, but if the other mod/datapack changes villages, it likely redoes these ugly and patchy savanna roads.
