modular doublets

no dependencies are required for this mod.
there are no meshes in this mod; it works for vanilla out of the box and should work with all upscales, provided they follow the vanilla mesh format.

polishing off some low-hanging fruit from my backlog and archives.

sensible, modular doublets. because there's 854679436 variants of this shirt and that they're not upgraded yet was driving me nuts (i had some ironworks ocs).
all doublets are now hooked into one material set, which has been updated to DT and includes dual dye. all toggles across the doublets can now be enabled/disabled through the mod, including belt buckle type.

the ironworks engineer has its own toggles because it requires a separate IMC file to include the decal, but still shares the same material as the rest.
