Fulgora extended

Adds more content to Fulgora and tweaks it in various ways to make it more intriguing. Places a greater focus on ruin salvage, scrap and byproduct production chains, and even ways to source small amounts of uranium. Will have the biggest impact if you are using the 'any-planet-start' (https://mods.factorio.com/mod/any-planet-start) mod and start on Fulgora. Note: Ice is scarce. Raiding ruins is your best source of ice, but scrap sorting still gives a tiny trickle. Notable features: Improved ways of obtaining holmium directly later on (requires forge technology). Expanded recycling from scrap with more useful outputs (We have infinite heavy oil. No need for solid fuel from scrap). Extended ruin raiding. A lot of larger ruins now have multiple levels to be fully mined. Fully mining the biggest ruins can get you some foundations and science packs. Deep oil oceans renamed to deep sludge abyss, with a new fluid an related recipes, and is impassible (also less of it on the map). You can dump items in deep sludge abyss (like lava) but don't inhale while doing so.
