fix static method

void fix(List<String>? names, String? data)

修正或追加节假日数据。节假日名称下标从0开始，超过9的，按ASCII码表依次往后排列；调休标识0为上班，否则放假 @param names 用于替换默认的节假日名称列表，传null即可使用默认名称 @param data 需要修正或追加的节假日数据，每18位表示1天依次排列，格式：当天年月日YYYYMMDD(8位)+节假日名称下标(1位)+调休标识(1位)+节假日当天YYYYMMDD(8位)。例：202005023120200501代表2020-05-02为劳动节放假，对应节假日为2020-05-01
