Crate volas_time 

volas-time: OHLCV time-frame cumulation (resampling) over the volas data model. Groups fine bars on a DatetimeIndex into coarser periods and aggregates each (open=first, high=max, low=min, close=last, volume=sum).

Depends on volas-core only — a sibling of volas-io / volas-directive with no cross-sibling coupling.
