getMajorStar function

List<List<FunctionalStar>> getMajorStar(String solarDateStr, int timeIndex, [ bool? fixLeap ])

安主星，寅宫下标为0，若下标对应的数组为空数组则表示没有星耀

安紫微诸星诀

• 紫微逆去天机星，隔一太阳武曲辰，
• 连接天同空二宫，廉贞居处方是真。

安天府诸星诀

• 天府顺行有太阴，贪狼而后巨门临，
• 随来天相天梁继，七杀空三是破军。

@param solarDateStr 公历日期 YYYY-MM-DD @param timeIndex 时辰索引【0～12】 @param fixLeap 是否调整农历闰月（若该月不是闰月则不会生效） @returns {Array<Star[]>} 从寅宫开始每一个宫的星耀
