Issue Description
The variants of the Oqaque Itemduct (Dense, Vacuum) have their recipies set to the same as that of the base Oqaue Itemduct. This makes them uncraftable.

Modpack version (Do not use "latest")
1.54

Screenshots

I can't get a screenshot that shows JEI giving the same recipe for all the Itemduct variants.

Fix
In scripts/ThemalDynamics.zs, set the NBTMatch parameter when calling remove on the recipe.

Opaque Itemduct dense/vacuum variants are disabled on purpose. The clear Itemducts still have the variants because they're more expensive.
Thanks for the report and fix anyhow!
