getHuoLingIndex function

Map<String, int> getHuoLingIndex(
  1. EarthlyBranchName earthlyBranchName,
  2. int timeIndex
)

获取火星铃星索引（按年支以及时支）

  • 申子辰人寅戌扬
  • 寅午戌人丑卯方
  • 巳酉丑人卯戌位
  • 亥卯未人酉戌房

起火铃二耀先据出生年支，依口诀定火铃起子时位。

例如壬辰年卯时生人，据申子辰人寅戌扬口诀，故火星在寅宫起子时，铃星在戌宫起子时，顺数至卯时，即火星在巳，铃星在丑。

@param earthlyBranchName 地支 @param timeIndex 时辰序号 @returns 火星、铃星索引
