Functions
auto	calendar::lunar::common::parse_lunar_year (int32_t year, uint32_t encoded) -> LunarYear
	Parse the encoded lunar year information for the given year. 返回给定年份的阴历年信息。
auto	calendar::lunar::common::month_position (const LunarYear &info, const uint8_t month, const bool is_leap) -> std::optional< uint8_t >
	Translate a traditionally-numbered lunar month to its 1-based position in info.month_lengths. 把传统编号的阴历月翻译成 info.month_lengths 里的位置序号（从 1 起）。
auto	calendar::lunar::common::month_at_position (const LunarYear &info, const uint8_t position) -> std::optional< TraditionalMonth >
	Translate a 1-based position in info.month_lengths back to traditional numbering. 把 info.month_lengths 里的位置序号（从 1 起）翻译回传统编号。
template<typename Func> requires std::invocable<const Func&, int32_t> and std::convertible_to<std::invoke_result_t<const Func&, int32_t>, LunarYear>
auto	calendar::lunar::common::calc_bounds (const int32_t start_lunar_year, const int32_t end_lunar_year, const Func &algo_f) -> AlgoBounds
	Calculate the bounds of the lunar algorithm.
