Invisible Slimes Icons & Extract Functionality Fixes

All changes below were ported over from tgstation/-tg-station, then patched for Paracode, and tested on a local server.

- Fixed pyrite, bluespace, sepia, and cerulean slimes, as well as their extracts not having sprites.
- Pyrite extract creates paint upon being mixed with 1u plasma
- Sepia extract creates a camera upon being mixed with 1u plasma, or camera film with 1u blood.
- Cerulean extract creates extract enhancer upon being mixed with 1u plasma, extract enhancer triples the number of uses of a single extract it is used on.
- Bluespace extract creates a bluespace crystal upon being mixed with 1u blood. Will be more useful once telescience gets updated.
