CLOCK_REALTIME may go backward, make generated uuid not sortable.

Normally uuid v7 generator will save last timestmap and use last_ts + 1 as current time if result of CLOCK_REALTIME is less then last timestamp.

for example:
https://github.com/google/uuid/blob/0e97ed3b537927cb4afea366bc4cc36f6eb37e75/version7.go#L97
https://github.com/lefred/mysql-component-uuid_v7/blob/924b55e37f406812ca7ce4d84d877e18e3fe53e3/uuid_v7.h#L130

will be fixed by #15
