Title: MasterWombatV2
Notice: MasterWombat is a boss. He is not afraid of any snakes. In fact, he drinks their venoms. So, veWom holders boost their (boosted) emissions. This contract rewards users in function of their amount of lp staked (base pool) factor (boosted pool) Factor and sumOfFactors are updated by contract VeWom.sol after any veWom minting/burning (veERC20Upgradeable hook). Note that it's ownable and the owner wields tremendous power. The ownership will be transferred to a governance smart contract once Wombat is sufficiently distributed and the community can show to govern itself.
Details: Updates: - pack struct - move pendingWom into UserInfo - use MultiRewarderPerSec
