A duel can finally tell you how round two went

A river race duel is up to three games recorded as one row, and Elixir has been telling people it could not speak to the games inside it - that a duel's tower hitpoints describe the final round only, that it has no elixir differential. That was true of what Elixir kept, not of what the game reports: the API sends every round separately, with its own crowns, tower hitpoints and elixir leaked, and Elixir stored each round's DECK while throwing the round's RESULT away. It keeps them now, and 20,218 rounds across 4,362 duels were filled back from the payload archive, so the history answers too. A duel row carries rounds[] beside its decks, on the same round numbers, each with its own elixir differential - the comparison the summed counter can never give you. Also in this version: global_rank on every participant, the global leaderboard position the API reported on that battle, so 'I was up against someone ranked 87th' is a thing the record can say.
