[L-1] Missing event in `MerkleAirdrop::claimFees()` function
Vulnerability Details and impact
Events allow changing the important parameters to be captured so off-chain tools/indexers can record such changes in an efficient way, allowing users and developers to analyze and evaluate them. The alternative way is directly querying the state of the on-chain contract for such changes, which is not considered practical for most users/usages.
MerkleAirdrop::claimFees() function is intended to be used by the owner to claim ETH fees that accrued from claimed airdrop tokens. This is an important state change and should be logged.
