Bite
Liquidate a vunerable CDP (zeros art, decreases ink).
Unsafe CDPs need to be liquidated. When a cup is not safe, anyone can
perform bite(cup), which takes on all CDP debt and confiscates sufficient
collateral to cover this, plus a buffer.
This returns the CDP to a safe state (possibly with zero collateral).
There are other possible implementations of bite, e.g. only taking
sufficient collateral to just transition the CDP to safe, but the
described implementation is chosen for simplicity.
