For playing with Krastorio 2 Spaced Out and Imersite Asteroids - https://mods.factorio.com/mod/Imersite-Asteroids

Changes the early Imersite technologies to require different Vulcanus/Fulgora techs:
- Crushing Imersite asteroids into rare metals requires the Asteroid Reprocessing tech from Vulcanus
- Advanced Imersite asteroid crushing requires Electromagnetic tech cards to have been discovered
- Imersium processing requires Metallurgic tech cards
- Advanced tech card requires Optimization/Metallurgic/Electromagnetic tech cards

there is an extra Startup option to move Fusion energy forward to Optimization tech cards
