 Packet fees are divided into 3 distinct amounts in order to compensate relayer operators for packet relaying on fee enabled IBC channels.
 
 - `RecvFee`: The sum of all packet receive fees distributed to a payee for successful execution of `MsgRecvPacket`.
 - `AckFee`: The sum of all packet acknowledgement fees distributed to a payee for successful execution of `MsgAcknowledgement`.
 - `TimeoutFee`: The sum of all packet timeout fees distributed to a payee for successful execution of `MsgTimeout`.
