feedback1 WB: bounty drafts and the 机密商店 from 66 official screenshots (22 matches)

Bounty drafts: every 悬赏决策 event is a fixed card list and the draft shows
6 different cards of it, drawn with weight 1 + the official drafts of its
group the card showed in.
- R3: 9 of the 10 fixed sets seen (two new: 20_1 + 20_5, and one with 17_6);
  3 x I + 2 x II + 1 x III in 22 of 22. The unseen 10th set is built by a
  rule whose III is 10_6 or 20_6, the only two-battle cards no draft showed.
- R9: 6 groups of 9 cards, one per bossInitial event. The 鼠王 group came in
  14 of 22 matches (every grey-board match among them), so groups are picked
  by the matches they came in. Named bosses no longer always come together.
- R11: lists of 7 cards, the draft leaves out one (matches 1 / 6 / 21 / 22
  leave out four different cards of one list); 7 of 15 lists seen, the rest
  and the 4 partial lists' 7th cards built by rule. Families 14 / 4 / 4.

机密商店 (the user: "机密商店按官方改成可以重复吧"): choices.json shopDraft,
six slots drawn with replacement - VI, VI, V, 盟约之币 and twice
V / IV / III / 盟约之币, items weighted by the official cards they showed on.
A repeated item now comes in about 61 % of shops (official 3 of 4). Two
identical cards stay two cards (picks by index): E2E, overlay and a
headless-Chrome test (game-mock ?variant=shop, the official match 8 shop).
