PROTO-73 [Bug]: BaseHook is broken after v4-core delta update

[tomwade]

Sorry, I wasn't able to create this as a PR, but the changes to make this fix are minimal:

• beforeAddLiquidity adds BalanceDelta param and BalanceDelta return
• afterAddLiquidity adds BalanceDelta return
• beforeSwap adds int128 return
• afterSwap adds int128 return

I have confirmed that this works on a local branch
