Farm Mutable

Purpose of change

Partially resolves #35212

New England's countryside doesn't spawn nearly enough farms, and the ones that spawn don't seem to produce much.
This PR adds a new type of farm - made with the power of mutables - that should hopefully negate the problems mentioned in the issue above.

Describe the solution

The mutable is made up of 9 phases:

1. farm entrance — the root of the mutable - connects to the farm house and the farm clusters
2. farm house — basically 3x3 Farm and farm_lot_forest
3. farm house extension (if farm house is farm_home_1) — adds either a greenhouse, silo or chicken coop to 3x3 Farm
4. farm cluster — 9x9 size farmlands that connect in a grid-like pattern
5. farm cluster edges (all) — connects to an unresolved join of a farm cluster
6. farm cluster edges (left) — connects to an unresolved join of a farm cluster (fallback for 5, in case it left out a join)
7. farm cluster edges (right) — connects to an unresolved join of a farm cluster (fallback for 5, in case it left out a join)
8. farm exit — adds a road connection to an unresolved join of a farm cluster (max 1)
9. fix unresolved joins — fixes any remaining unresolved joins with a dummy join

A finished mutable looks something like this:

The building blocks that make up the mutable mainly use the general-purpose tiles I made back in #31188, which have been expanded with newer mapgen (like hay- and cornfields), and updated (dirt roads) to better suit the new farm.

Some of the farms with lower crop yields ( farm_lot_wired_2x3, farm_lot_empty_3x2, farm_lot_2x4 ) have been obsoleted. The mutable has made them redundant.

farm_lot_forest, Farm, Farm with silo, Farm with chicken coop and Farm with greenhouse are now incorporated into the mutable. They no longer spawn separately.

Other farms, like farm_horse, St_Johns_farm, farm_2side and farm_stills are unaffected by this PR.

Describe alternatives you've considered

• not obsoleting the old farms
• obsoleting the old farm fields in farm_tiles.json
• adding farm_2side and farm_stills to the available building types
• differentiating silos and grain bins
• adding more variations: pastures, vegetable fields, sheds, etc...
• (I know very little about proper plowing patterns)

Testing

Created a new world, surveyed the land for farm mutables.

This is amazing, fantastic work!

I'm having trouble seeing what monsters would spawn in these specials. Am I missing the spawns?

Only the farmhouses and orchards have set spawns. Farm fields and dirt roads don't spawn any monsters.

This is beautiful, thank you

These look super cool. I am really looking forward to coming across these.

Obsoleting most of the old farms is cool.

I was wondering how much variation in size this caused?

I know for orchards that they tend to be smaller and more self contained more often than grains like corn and such which take massive amount of land to make sense. Since the most efficient way to farm stuff like that is with big tractors. But, orchards are often still pretty compact

Because of how randomized everything is, I can't really put an exact number on this; I've seen farms ranging from 80 to 1120 OM terrains large. Depends on how many puzzle pieces there are.

I happen to live in a very agricultural region and have seen orchards like these, plopped in the middle of farm fields. Thought there'd be no harm in representing stuff like this in the game. They also help break the repetition, which is nice.
