Add builtin compat with Repurposed Structures

[TelepathicGrunt]

This will add to Repurposed Structures's villages automatically. The way it works is the special rs_ folders are read by Repurposed Structures and automatically does the piece injection. No code needed on your side.

Note, I setup the houses differently than what you currently do. I have 1 house for every village type. And then have an inner jigsaw that spawns a random workstation. This way I do not need multiple copies of the same house just to change the workstation and makes adding new workstations easier.

If you wish to have these files only apply when a config is set to true, you would simply grab the repurposed_structures:json_conditions registry on each loader and then add the "condition" field in the rs_pool_additions and rs_pieces_spawn_counts json files to point to the condition you registered.
