Unsafe Function receiveFees  Acknowledged
In the Pool contract, function `receiveFees` is used for compensate a potential penalty/slashing in the protocol by sending LYX back to the pool without minting sLYX, but the side effect is that anyone can send LYX to the pool which could mess up pool balance after all validator exited, in fact it can be replaced by a another function `receiveWithoutActivation` with access control which does the same thing.\\n```\\nfunction receiveFees() external payable override {}\\n```\\n\\n```\\nfunction receiveWithoutActivation() external payable override {\\n require(msg.sender == address(stakedLyxToken) || hasRole(DEFAULT\\_ADMIN\\_ROLE, msg.sender), "Pool: access denied");\\n}\\n```\\n
Remove function `receiveFees`
```\\nfunction receiveFees() external payable override {}\\n```\\n
