afterInitialize = trueRuns custom logic before liquidity is added, and can block deposits.
beforeAddLiquidity = trueRuns custom logic before every swap. It can change the fee or block the trade.
beforeSwap = trueRuns custom logic after every swap.
afterSwap = trueCan take or add tokens to a trade's output after the swap executes.
