[idea] Rework Blood system

[Gomp]

As far as my doctoring experience goes no one actually uses blood packs, everyone just uses saline, I do like the idea of making blood transfusions more complex but I don't think blood types would add much besides maybe ressource scarcity, the trivial task of using the right blood (you don't need to worry about compatibility if you just take the same type) is not really going to add anything.
I like the idea of side effects, mostly because it sounds like it would give roboticists more patients.
