TrackerReceiver checking for checksum verification
TrackerReceiver module is now able to use information from TRBEventDecoder about checksum verification. Added new metric variables which keep number of checksum mismatches (i.e. corrupted events), rate of checksum mismatches (erroneous events/total number of decoded events), total number of decoded events.
Also fixed one bug with memory leak that was discovered by lucky coincidence. Bug appeared only in DEBUG mode while printing raw data that are sent further in FASER DAQ.
