Relays contains duplicate relays

example - # epoch 226729, consensusSlot 7255338, executionBlockNumber = 18067890

There are 24 relays in the row value. A lot of them are duplicates, there are really only 8 unique relays {'aestus', 'agnostic', 'blocknative', 'bloxroute_maxprofit', 'bloxroute_regulated', 'edennetwork', 'flashbots', 'ultra_sound_money'}

This is a reoccurring problem in the dataset
