This queries two different nodes for /namespaced_data/[8]{0,1,2,3,4,5,6,8} at daHeight between os.Args[1] to os.Args[2] then iterates over any Optimint blocks within the Celestia blocks and prints the heights.
Run with
go run main.go 55200 55200
daHeight: 55200, bridgeHeight: 1941, fullHeight: 1941
