Oversized Quirk Buffs (#4482)

# To be merged after #4479 

## About The Pull Request
Oversized people have very few upsides, their duffelbag slowdown mixed
with their huge sprite size means they are are absurdly vulnerable to
just about any melee fight.
This PR increases their health to 140 from 100.
Or, if this PR is mistakenly merged before #4479 then to 189 from 135?

## Why It's Good For The Game
Balances out the significant downside of oversized.
Makes oversized more roleplay-friendly; someone that big shouldn't be
just as weak as a 4ft catboy.

## Proof Of Testing

It's 189 because the other PR hasn't gone through yet. Once it does,
it'll be 140.
