    Implement to emit D-Bus signal for PLDM Event Messages. PLDM Event
    Messages are PLDM monitoring and control messages that are used by
    a PLDM terminus to synchronously or asynchronously report PLDM events
    to a central party called the PLDM Event Receiver.

    When the PLDM daemon receives a sensorEvent of type stateSensorState,
    it emits the StateSensorEvent signal.

    This signal would be used by PLDM Requester apps on the BMC, which
    will rely on this signal to determine state changes on a connected
    PLDM entity.

    More information about PLDM Event Messages can be found at DSP0248
    version 1.2.0 section 13.

                within a terminus.
