§method: u8雪花计算方法,(1-漂移算法|2-传统算法),默认1
base_time: i64基础时间(ms单位),不能超过当前系统时间
worker_id: u32必须由外部设定,最大值 2^WorkerIdBitLength-1
worker_id_bit_length: u8默认值6,取值范围 [1, 15](要求:序列数位长+机器码位长不超过22)
seq_bit_length: u8默认值6,取值范围 [3, 21](要求:序列数位长+机器码位长不超过22)
max_seq_number: u32设置范围 [MinSeqNumber, 2^SeqBitLength-1],默认值0,表示最大序列数取最大值(2^SeqBitLength-1])
min_seq_number: u32默认值5,取值范围 [5, MaxSeqNumber],每毫秒的前5个序列数对应编号0-4是保留位,其中1-4是时间回拨相应预留位,0是手工新值预留位
top_over_cost_count: u32最大漂移次数(含),默认2000,推荐范围 500-20000(与计算能力有关)
seq_step: u8生成流水序列之间的步长,默认为1。
