/**
* @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.
