最近测试PCF8563T芯片的时候使用本库时发现默认例程在走时几秒后就出现输出不正确的情况，如开始时间[2023-11-04 16:02:27.206] I/user.time	2023	11	2	13	14	15	week=2，走时5秒后输出[2023-11-04 16:02:32.211] I/user.time	2023	31	2	13	14	20	week=2，后面的走时更加错误，如[2023-11-04 16:02:52.293] I/user.time	2023	51	42	53	14	40	week=42。经查发现是pcf8563t.read()里在处理数据与时与到了不需要位，导致bcd_to_hex(data)时出现错误。按datasheet修改7个字节中每字节需要保留的位数，暂时测试正常。
