* @brief This class should be used with the TcpTmTcServer to implement a TCP server
* for receiving and sending PUS telemetry and telecommands (TMTC)
* @details
* This bridge tasks takes care of filling a FIFO which generated telemetry. The TcpTmTcServer
* will take care of sending the telemetry stored in the FIFO if a client connects to the
* server. This bridge will also be the default destination for telecommands, but the telecommands
* will be relayed to a specified tcDestination directly.
