[SE] Unwanted science packs ingredients

With my [WH40k Titans mod](https://mods.factorio.com/mod/WH40k-Titans), SE adds unwanted science packs ingredients. I used `se_prodecural_tech_exclusions` variable, it worked for most of researches excluding "Titans production" which still gets affected. I reviewed and experimented with code of SE and post-process and found out that at the beginning of `phase-3.technology-procedural.lua`, the `space-science-pack` is already added, so the script adds rocket pack, but I cannot find the source of space sci pack addition.

This is not urgent as I made a simple workaround – overriding ingredients at phase-3 of my mod.
