[MIRROR] Rebalances bz, makes it less of a self antag tool (#3311)

* Rebalances bz, makes it less of a self antag tool (#56832)

Makes hyper low amounts of bz not cause hallucinations
Makes the brain damage portion of bz breathing only take effect at higher pressures, roughly 10 mols at room temp on a turf

* Rebalances bz, makes it less of a self antag tool
