fix(dup_blocks_test): convert to benchmark
Browse files Browse the repository at this point in the history 
So that CI passes, and because it's not reliable as a test, and is more a benchmark to measure
performance, convert dup_block_test.go to a benchmark, which can be run using `go test -bench .`
