Get segment win rates

Deprecated: use discovery.segment-win-rates.get.v2 (discovery_segment_win_rates_get_v2), which answers the results window its rates read in scope.window and an all-up rate nothing in scope measured as { kind: absent, reason }; this version reads the same rates, names in scope.dispatchId the newest run that measured a conversation of the window's last 30 days, reads an absent all-up rate as 0, and labels the window's as-of day in measuredOn ("Oct 9"). Read a campaign's brand win rate for each revenue line and each audience, with each split's all-up win rate, exactly as discovery.revenue-reports.get and discovery.audience-reports.get state them for the same window, read as the campaign's own brand. Carries no trend, driver or competitor: the reports carry those.
