Deprecations
- In _periods.Instant_:
- Remove `period`, method used to build a `Period` from an `Instant`.
- This method created an upward circular dependency between `Instant` and `Period` causing lots of trouble.
- The functionality is still provided by `periods.period` and the `Period` constructor.
Migration details
- Replace `some_period.start.period` and similar methods with `Period((unit, some_period.start, 1))`.
