NC001 - Functions Mutating Storage Should Emit Events

Functions mutating storage should emit an Event for easy off-chain monitoring.

🤦 Bad:

function setFee(uint256 _fee) external onlyOwner {
    fee = _fee;
}

🚀 Good:

function setFee(uint256 _fee) external onlyOwner {
    emit ChangedFee(fee, _fee);
    fee = _fee;
}
