Gen Flood early review

[pizzaman1337]

Floods every whitelisted well (if necessary) to return deltaB to zero. Floods necessary wells to the same deltaB level. Pays off 0.1% of Bean's market cap worth of podine per flood (rather than flooding entire podline). Adds Flood forge test based on initial hardhat test. Removes original flood event in favor of one event emitted per-well flooded, and one for flooding the field.

Remaining todo: only flood when L2SR is at a certain level.
