Brain - Add Brain Simulation and Traumatic Brain Injuries

[apo-tle]

When merged this pull request will: This PR implements a high-fidelity simulation of brain function into KAT Medical. All relevant factors, including blood pressure, intracranial pressure, cerebral vascular resistance and brain oxygen saturation are considered in order to calculate a value for cerebral metabolic rate. CMR below safe values causes various effects such as dizziness, loss of consciousness, heightened emesis and seizures.

To Do List

• [x] Cerebral Metabolic Rate
• [x] Cerebral Blood Flow
• [x] Autoregulation
• [x] Brain oxygen saturation
• [x] Tissue necrosis
• [ ] Seizures
• [x] Concussions of varying severity, causing raised ICP
• [ ] Side effects for low CMR
• [ ] Benzodiazepines
• [ ] Ondansetron
• [ ] Fix localization
• [ ] Fix dependencies

I've completed the hardest parts of this PR already, so I don't intend there to be a massive wait between opening this draft and finishing.

Is it possible to flag units as "immune from brain damage" or "lacks enough brain to damage" ?

Would be really smart if i came with a setting to turn this on or off, like kidney failure.
