/**
 * @brief   This class can be used with the UdpTcPollingTask to implement a UDP server
 *          for receiving and sending PUS TMTC.
 * @details
 * This bridge task will take care of sending telemetry back to a UDP client if a connection
 * was established and store them in a FIFO if this was not done yet. It is also be the default
 * destination for telecommands, but the telecommands will be relayed to a specified tcDestination
 * directly.
