Implement proper buffered iterator

This adds a proper duration based lookback buffer for series iterators
to allow advancing sequentially while remaining able to calculate time
aggregating functions such as `rate` backwards.

It uses an array ring buffer to minimize heap allocations for
potentially hundreds of thousands of series for a single query.
