Rich Rocks are back!

This mod brings the Rich Rocks ore, item, research and processing from Krastorio Legacy and ports them to Krastorio 2.

All recipes have been left unchanged, except for the removal of Menarite and Gold from the Raw Minerals and Raw Ores processing recipes respectively.

If Industrial Revolution 2 is enabled, processing of Raw Ores will produce sulphurous gas, as well as Tin Ore, Gold Ore and Crushed Rare Metals, and the processing of Raw Minerals will produce sulphurous gas and gem powders (5% chance of sapphire and ruby powder, and 1% chance for diamond powder).

In addition, I have changed the icons of Raw Rare Metals because the icons for Raw Ores and Raw Rare Metals were exactly the same. Raw Rare Metals now have a colour scheme that better reflects the colours of Rare Metal ingots. The colour of Rich Rocks patches on the map has been changed to a much brighter turquoise colour as the old purple looks too similar to that of Rare Metals patches.

Most of the code used in this mod was lifted straight from the Krastorio 1 codebase, as well as most of the icons and recipes.

NOTE: Does not work with RSO at least for the time being, that is. Adding RSO will completely prevent Rich Rocks from generating in your world.

Any and all feedback is appreciated.

To do:

• Add user settings to customise the recipes (e.g. turning off special IR2 recipe changes)
• Add integration with Space Exploration
• Further balance the recipes (if needed)
• Add RSO support (once I figure out how to)
